How To Clean Lava Rocks For An Aquarium

Decorating your aquarium is called aquascaping. It's kind of similar landscaping, just under water!

In freshwater, aquascaping makes use of alive or plastic plants and driftwood. Marine fish aquariums ofttimes employ expressionless coral skeletons every bit decorations. But ane of the most interesting edifice materials for aquariums aquascaping is stone materials.

Rocks can create a sense of depth and dimension to any aquarium. It gives fish a place to explore and even observe microscopic alive foods like algae and bacteria. A stone cave volition create a prophylactic hideout for shy catfish. Rocks even provide a flat surface for egg-laying African cichlids and angelfish. In reef aquariums, chunks of reef stone are the foundation for the unabridged tank's ecosystem. It also provides a place for invertebrates like stony and soft corals to form colonies.

But non all rock materials are appropriate for aquarium use. It too depends on the type of aquarium and the range of aquatic life. We'll examine the types of rock you lot can use in freshwater and marine aquarium. Then we'll hash out how to utilize these rock-based materials to create a fun and attractive aquascape.

Types of aquascaping stone

You'll observe many different types of stone and stone materials available in pet shops, online and fifty-fifty in nature. But not all aquarium-rubber rocks are right for every aquarium. Let's start by taking a close wait at the types of rock materials you'll probable see when searching for aquascaping materials.

A give-and-take of circumspection

The about of import factor to bank check out when selecting decorative rocks is if the rocks are inert in aquarium water. Some rocks will release calcium into the water. This raises water hardness, which tin can be undesirable in planted aquariums and when keeping Amazonian fish.

The rock may release carbonates, which will increase the pH and fight confronting all your efforts to keep it in the neutral to slightly acidic range. But these rocks are quite desirable if you've got an African cichlid aquarium, which benefits from harder water and a higher pH.

one. Slate and shale

You'll find pieces of slate and shale offered for aquascaping in any pet store and on line. At first glance they may announced similar but there a few interesting differences.

Shale is a sedimentary rock made of clay, quartz and other minerals. These ingredients were pressed downwards and compacted for millions of years, forming what we phone call shale.

Shale can be blackness, grey, blood-red or even yellow depending on slight variations of the mineral content. You can easily break shale with a soft tap with a hammer. When shale is buried under more than sediment for a longer time, it creates slate.

Slate can besides form from volcanic activeness. Like shale, slate tin vary in color (dark red, grey and dark-green) or have streaks of color. Most slate sold for aquarium is grey. Slate is much harder and stronger than shale, it is commonly used to make pool and billiard tables. Y'all can also discover slate cut into thick pieces for making outdoor walkways, and for indoor flooring. Slate is also used to make durable shingles for roofs.

You lot'll observe slate is harder and stronger than shale. It's the most common rock offered for aquariums. Slate is sold as apartment slabs ranging from a few inches long to over 12 inches.

These rocks are inert and won't change the pH or h2o hardness. Slate is peculiarly useful in freshwater aquariums to build ledges and cliffs.

2. Lava rock

Volcanic rock, likewise known every bit lava rock, is a popular aquascaping material for aquariums. Lava stone forms when gasses in magma begin to solidify and harden.

Lava rock is very porous. Y'all tin see the thousands of pits and pockets formed past the gas bubbling. This rock has a variety of uses. It'south crushed and used for pathways, construction of baseball fields and even in firepits and gas grills. It's relatively strong but tin can exist broken with a hammer.

Volcanic stone comes in several colors including black, brick red, light cerise and deep orange. In the aquarium trade large lava rock chunks are shaped by sandblasting to create arches and rocks with a hole through the center.

Lava stone won't release calcium or carbonate into the aquarium water. Information technology's great for all types of freshwater aquariums.

3. Quartzite

When quartz sandstone is heated and compressed, information technology forms the mineral quartzite. Fe oxide, silica, carbonate and dirt create an attractive streaking pattern. Quartzite is used on railroad beds and for decorative purposes on walls and walkways. You'll find polished quartzite used for kitchen counter tops.

There are many trade names given to the natural colour patterns in quartzite rock. Yous may meet it sold as Onyx bamboo, Platinum black and Glacier wave. These are just fabricated-up names given to the color variants of quartzite. Your aquarium supplier may fifty-fifty brand up their own names.

Quartzite is safe for soft water planted tanks and freshwater aquariums.

4. Petrified wood

Petrified wood is considered a fossil. Information technology forms when trees are buried under sediment. They don't decay due to lack of oxygen. But when groundwater slowly flows through the sediment, the original wood is replaced with minerals like with silica, calcite, pyrite, and other inorganic minerals like opal. Once the original wood is flushed away and replaced with minerals, you go petrified wood.

The rock may even evidence patterns of the original tree bawl or grain patterns. Most petrified forest sold in the aquarium trade looks like a branch cut into a log or shorted segment. The color design is usually grey-black or cerise orange.

This unusual inert rock makes a great addition to freshwater aquariums. It won't have any touch on water chemistry.

5. Drinking glass rock

Glass or fire rock is man-made and comes in a variety of colors and sizes. It's used in landscaping, lining of ornamental streams and in gas fire pits and fireplaces. You lot'll notice a total range of colors from black to turquoise bluish. Some aquarium supply dealers stock large "chunks" of colored glass. They look similar a large gemstone and are used every bit a focus point or accent in the aquarium.

Drinking glass rock can be used every bit a gravel substrate or blended into traditional gravel to add contrast. This rock won't modify the water chemistry.

6. Texas holey rock

As the proper noun implies, this natural stone is found in Texas and it has a lot of holes. Holey Stone is made of limestone and will slowly make your h2o harder and increase the pH. That'south why Holey Rock is a favorite amidst African cichlid fans.

The stone helps to keep the water chemistry more than similar the African Rift lakes. The holes brand great hiding places and escape routes for the fish. In no time they'll set upward their personal hole as a dwelling house and defend information technology from unwanted visitors. It gives the cichlids a sense of security besides.

seven. Rainbow stone

Rainbow Rocks are quite colorful, unremarkably white and orange or white with red and green. These sedimentary rocks are mined in Mexico. The rocks are sometimes sandblasted to create a hole in the center. Rainbow Rock does not look natural but it is popular with aquarists.

It is inert and won't alter the pH, carbonate hardness and general hardness. Rainbow rock is most often seen as a decoration in freshwater aquariums.

8. Mountain Stone

Mountain Rock was fabricated famous in Takashi Amano's planted aquariums. The stone'southward colour ranges from nighttime to light gray. This stone is used to create rocky landscapes that remind yous of a mountain in miniature. It contains calcium carbonate and volition add some hardness and pH-increasing carbonates to the water.

Mount Stone is ordinarily used sparingly as a focus betoken in the aquascape. Information technology too limits the amount of water hardness added to the h2o. Many planted aquariums use carbon dioxide fertilization, which will help keep the pH lower during the daylight hours.

Some aquarists soak the rock in dilute hydrochloric (muriatic) acid for a few days. This handling reacts with the carbonates and reduces the amount of carbonate added to your aquarium. This process requires cracking intendance including gloves and eye protection.

nine. Plastic rocks

Some freshwater aquarists like to use plastic resin "rocks" instead of real rocks. The resin rocks are molded from plastic and come in natural stone colors. They oft sold as stackable kits that lock the pieces together.

The benefit of resin rocks is that they are very light, don't add anything to the aquarium water and are easy to remove and clean when necessary. Planted aquarium enthusiasts tend to get with real rock since plants like Java moss and Anubias find it easier to adhere to natural rock surface. Plastic stone is popular for aquascaping small aquariums.

Rock for saltwater aquariums

We've focused mostly on rock for freshwater aquariums. Saltwater aquarists desire to use decorative materials that come from the ocean. Dead coral skeleton is made of calcium carbonate but information technology's not really stone, altough it'south sometimes used in fish-only aquariums.

The largest users of rock are reef aquarists. They utilise calcium carbonate rock that is cleared from aircraft lanes around tropical sea ports or mined from ancient deposits. Natural reefs are created past reef-edifice corals and encrusting algae. The marine life removes calcium and carbonate from the water and uses it to build a dense calcium carbonate skeleton.

Over many years reef stone is congenital past nature. This stone is used to recreate a reef in a marine aquarium. Base of operations-type rock is stacked into a pile or life-like construction. There are several types of reef rock bachelor today.

i. Fiji Rock

Republic of the fiji islands Rock is the most common type of alive rock used in reef tanks. Information technology's relatively lite weight and easy to handle. Fiji rock is usually boat-shipped, which can take upwardly to 30 days to arrive at the supplier's warehouse or fish store. Much of the marine life on the rock will not survive the long trip. This means the stone has to be soaked in saltwater for a few weeks to flush the decomposable marine life from the rock. Air shipments are possible but very expensive.

two. Tonga Branch Rock

Tonga Branch is a denser, heavier rock. The antler-like shape adds an interesting dimension to the layout and is all-time used equally accent pieces. Information technology's used to supplement the less-branched base rock. Tonga Branch Rock is frequently coated with live pink and purple encrusting algae.

3. Pukani Stone

Pukani Stone is from Fiji but is lighter than regular Fiji stone. Pukani is quite porous. The surface is total of depressions and crevices that are slap-up places to attach coral frags. The live rock frequently has a coating of encrusting algae. Dry Pukani is a great building material and will eventually become coated with marine life. It'south available in larger pieces and is easily stacked to create stable shelves for corals to abound on.

4. Aquacultured Live Rock

Aquacultured live rock starts as either pieces of calcium rock or homo-made rubble. It is scattered in the ocean and left for several years. Over time the rock becomes colonized with marine life and looks like natural live rock. Aquacultured live rock is sustainable and does not damage the reef ecosystem. It usually comes from the Gulf of Mexico or the Atlantic Ocean. That means it arrives fresh and in adept condition.

5. Dry Rock

Dry out rock is stale live stone harvested from the body of water. Even though it is completely dry, it volition leak nutrients and organics as the expressionless marine life decays in the water. Information technology should be cured like live rock. Check the water for ammonia and odors during the curing process.

6. Life Stone

Life Rock is stale reef rock with a purple coating that looks like coralline algae. It gives a newly set-upwardly reef tank a colorful appearance right away. Over fourth dimension living coralline will cover the rock as the tank matures. Life Rock requires no curing.

Using rocks found in nature

The internet is full of warnings about using rock materials from natural streams or quarries.

The rational is that rocks in the environment are loaded with diseases that will impale your fish. Rocks and pebbles collected from freshwater systems will contain a coating of biofilm comprised of algae, leaner and microscopic worms.

It is very unlikely that you'll introduce a parasite or bacterial disease from rock nerveless from a freshwater source. There is a much greater chance of adding pathogens to your aquarium when you lot add new fish than on "wild" rocks. Merely that doesn't mean all rocks are suitable for the aquarium.

Reef and marine aquarists aren't going to utilise freshwater rocks in their tanks, so we don't need to discuss that scenario.

If you're going to use rock from nature, be sure it's non in a contaminated location. It would exist foolish to select rocks from a polluted stream or an industrial expanse. If the rock is covered with algae, it may make a great alive food source for herbivores similar pleco cats. Merely it could besides innovate algae into your tank.

The other concern is the presence of limestone in the stone. If yous're keeping a soft water Amazonian biotope, limestone rocks will gradually raise pH, hardness and alkalinity (carbonate hardness). Trying to maintain a community freshwater aquarium with a medium hardness and close to neutral pH could be hard with limestone-rich rocks.

Testing rocks for carbonates

The easiest way to test for carbonates is with a liquid "pH Downward" production.

The elementary non-buffer pH lowering liquids are fabricated of dilute sulfuric acid. Add a few drops to the rock and look for bubbles and foaming. If the rock foams, it means the carbonates are reacting with the acid.

These rocks will be great in an element of group i African cichlid tank or even a brackish aquarium. Only if y'all're trying to go along the h2o soft and pH at 7 or below, avert carbonate rocks and stones.

Washing and workout rock

Whether yous're starting with new stone from the pet supplier, reconditioning old aquarium rocks or using rocks from nature, it'south possible to make clean them upwardly before placing the stone in your tank. We'll outline the most mutual methods from easy to extreme.

1. Scrubbing with a brush

The easiest manner to clean up a rock is to scrub it with a brush under running tap h2o. Scrubbing loosens up organic matter, soil, algae and rock dust from aircraft. Information technology's also a way to clean upwards rocks that have become dull or dirty after sitting in your aquarium.

ii. Soaking in pure h2o

Soaking rocks in distilled or reverse osmosis water may allow some hardness minerals to dissolve out of the stone. Carbonates locked into the construction of the rock won't commencement bubbling or be neutralized by pure h2o. Soaking can help flush loose minerals out of cracks and pores, but it probably won't prevent a stone loaded with limestone from adding hardness and raising the pH.

three. Washing rocks with boiling h2o

Soaking the rock in boiling h2o volition kill the biofilm and eliminate any fears on introducing "something bad" into your tank. It will also loosen dried dirt and other organic matter. Humid water can restore a rock or stone's natural beauty.

Exist careful pouring hot h2o as it tin splash and fire your peel. Some aquarists warn that boiling stones may cause them to fracture or "explode." Even if the explosion story is a myth, why take the chance damaging your rocks. Just use hot tap water instead of boiling h2o.

4. Bleaching rock

If you're really worried that your rock is going to introduce an unwanted life form, bleaching will kill everything and loosen up organic thing. A dilute bleach soak works for rocks and plastic plants. Just be careful not to splash the water onto your clothes, carpet or eyes.

In one case the soak is complete, it'due south necessary to rinse abroad the remainder bleach. Yous can either flush the rock with several buckets of water or allow the rocks to dry in the sunday. Chlorine bleach will break down as the rock dries.

v. Acid washing

Soaking rocks in dilute muriatic acid (hydrochloric acid) is the "nuclear pick" used to neutralize rocks containing some carbonates. Handling acid can be quite risky. It volition fire your optics, nose and skin. Splashes volition consume through your clothing. Once the acrid bath is complete, you'll have to neutralize the acid for safe and environmentally responsible disposal.

Aquascaping with stone in freshwater aquariums

Rocks and stones have always been popular decorative materials for freshwater tanks. Minor smoothen pebbles add diverseness to an otherwise apartment gravel bed. A single beautiful stone or piece of glass volition create a beautiful centerpiece in a betta aquarium.

While at that place are no prepare rules for aquascaping with stone, there are a few things to consider. When stacking stone or making caves and overhangs, make sure the rock pile is stable. A rock collapse can crack the aquarium glass or damage a heater. You lot tin can employ an aquatic epoxy glue that cements the rocks together, even under water. This special epoxy is sold for mounting corals onto carbonate rock in reef aquariums.

Reef rock and saltwater aquariums

The majority of aquarists using reef rock are edifice a reef aquarium. The idea is to form a stable base for attaching coral frags, soft corals and other marine life. You can utilise reef epoxy to stabilize your rockwork for a secure structure.

Pop aquarium rocks

Here'due south a list of readily bachelor aquascaping rock for freshwater aquariums, marine tanks and reef aquariums. Yous may find others simply these are some of the most popular types of aquascaping rock in the aquarium hobby.

1. Seiryu Stone

Also known as Dragon Rock, Seiryu Stone is native to Nippon. It's illegal to import true Seiryu, merely convincing await-alikes are available. The stone is blue with veins of calcite. This means the rock will gradually heighten pH and water hardness if you use a lot of it.

ii. Natural slate

Sold in small pieces of 1 to 3-inches, this natural slate will work every bit a rugged gravel bed or emphasis substrate. The pieces are small enough to brand tiny ledges. You lot can also epoxy the slate to the back of the aquarium, forming a rock wall.

3. Aqualexs Aquarium Ohko Dragon Stone

This rock has a mount-like shape only with a cherry-orangish tiny and contrasting veins. They make a great focus indicate whether used lone of in multiples. This style of rock is pop with minimalist aquascapers. They'll use depression-growing plants, giving the rock the appearance of a mountain ascent above the wood.

four. CaribSea Southward Bounding main Base Rock

This reef rock is fully cleaned and sun-cured. No conditioning is needed. Merely accommodate the pieces in your marine or reef aquarium and permit nature take over. S Sea Base of operations Rock makes a fine foundation for building your reef tank. Coraline algae will eventually grow over the rock, giving it an attractive purple and pink color. You tin gum SPS and LPS corals directly to this stone with reef epoxy.

v. Billy's Dry out Reef Stone

This porous reef rock originates from Florida. Each piece is paw-selected from an inland quarry containing old reef materials. The rock is power-done to remove dust and droppings. This rock is fully cured and ready to utilise in a reef tank or African cichlid aquarium.

6. CaribSea Life Rock

Life Rock starts out as South Sea Base of operations Rock but receives a purple and pink coating. This makes the rock look like it's covered with coralline algae. This gives your new reef a seasoned look. Eventually the rock will get coated with living coralline algae and corals equally your aquarium matures.

7. Beachcombers Coral Centerpiece

If you've got a fish-but saltwater tank, a coral centerpiece volition add depth and curiosity to the aquascape. The bright white skeleton gives the aquarium a focal signal and a place for fish to swim around.

Aquarium Rock Recommendations

Aquascaping is a personal choice. Some aquarists like information technology bold and colorful. Others go for the subdued, natural wait. Smaller aquariums will need smaller rocks to await right in the tank. If y'all've got a big aquarium wait for larger rocks or build your own rockwork.

Slate has ever been a popular cloth in freshwater aquarium. Tropical fish love to explore the caves and ledges.

More exotic Dragon stone-type rock brand for an unusual aquarium where the aquascape is the chief focus.

Many reef aquarists are starting their aquariums with dry stone like CaribSea Life Stone. They like the idea of not having to let the rock cure. It makes new aquarium prepare-up fast and easy and you don't have to worry about die-off polluting the water.
