Does lava rock increase water pH?
Keeping the proper pH level is essential for maintaining a healthy “mini-ecosystem,” so you may be wondering if adding something like lava rock will affect these levels or cause any other types of changes. Lava rock is often a pH neutral substrate.
Does lava rock alter water parameters?
No, lava rocks don't alter the water's pH, nor do they affect the water's chemistry in any way. Except, of course, if you ignore the rocks' effect on the nitrate levels. These rocks are generally safe for fish and plants. I say 'generally' because they might not be in some instances.
Are lava rocks pH neutral?
Lava rocks are typically pH neutral, porous, and provide good drainage and aeration to the system. While lava rocks are a popular grow media option in aquaponics, it also has some downside.
Does lava rock effect aquarium water?
Lava rocks are covered by holes and pores that have beneficial bacteria, which is called denitrifying bacteria. These bacteria can help in keeping normal nitrogen cycles in your aquarium. These bacteria help break nitrate to form oxygen and nitrogen and help your fish grow in a cleaner and much healthier environment.
Does lava rock change water chemistry?
Nope, it's inert.
What rocks will raise pH in aquarium?
Limestone is calcareous (contains calcium) and is known for its ability to both harden the water and increase the pH. In fact, if someone asks how to raise water pH, one method we suggest is to place crushed limestone, coral, oyster shell or any highly calcareous material in the filter.

Lava rock, basalt, granite, slate, quartz, flint, quartzite, and obsidian are all perfectly safe.
Does black lava rock increase pH?
In general, most lava rock is basically the same stuff as basalt, just with bubbles in it. by itself, it should be rather inert, and not affect pH.
Does lava rock remove nitrates?
In any case, it won't remove nitrates. While for a time (until it gets clogged) it will harbor bacteria that will convert Nitrites to Nitrates, the nitrates still need to be either consumed (plants, etc.) or removed (water changes).
Does lava rock make good filter media?
Lava rock – the igneous rock that forms as an erupting volcano's molten lava cools and hardens – is very porous. When chunks of it live in your filtration system, you provide a lot of surface area for beneficial bacteria to colonize and grow. That's what makes it such a great filter media.
Is lava rock acidic or basic?
AcidicAcidic Lava may be erupted at a volcano or through a fracture in the crust, on land or undersea. Usually, the temperatures range from 800 to 1,200 °C (1,470 to 2,190 °F). The volcanic rock resulting from subsequent cooling is also often called lava....Acidic Lava.Other Relevant LinksBasic LavaTypes of Volcanoes2 more rows
Is lava basic or acidic?
Basic lava is non-acidic and less viscous. Basic Lava flows for long distances before solidifying, it has gentle sides. Basic lava has a high iron and magnesium content but a low silica content. It has a darker appearance due to its high concentration of ferromagnesian minerals.

How does lava rock filter water?
Lava rock is a common filtration media in aquariums and ponds, where the porous surface of the stones creates greater surface area where the biofilm can accumulate and act as a filter for bacteria.
Do I need to boil lava rock for aquarium?

Is volcanic rock acidic?
In areas of major mountain-building activity, granitic magmas are formed by anatexis or metasomatic processes working at depth and some of this liquid finds its way to the surface, producing the acidic volcanic rocks.

For example, if your pet fish thrive in a pH of 7 but your aquarium measures 8, your water is 10 times more alkaline then it should be. If the pH is 9, then your fish are living in water that is 100 times more alkaline then it should be.
Why are lava rocks good for fish tank?
As I had mentioned, lava rocks are porous hence perfect for providing the ideal living environment for beneficial nitrifying bacteria. These bacteria are crucial in all fish tank environments as they are responsible for breaking down excess nitrates, and expelling them from the water column.
Why do lava rocks change water parameters?
Because lava rocks are inert, the substrate will rarely cause changes in your water parameter, albeit some fish keepers believe the rocks do release undesirable gases and trace metals from their structure into the water.
What to use to bulk up aqua soil?
Under the substrate, use lava rocks to bulk up your aqua soil as an alternative to power-sand or to substitute aqua-soil when you need to create a slope inside your fish tank.
Why are my aquarium rocks red?

Why does pH change in aquarium water?
Over time, the pH in the aquarium water will change due to the chemicals produced by the fish and bacteria in the aquarium. It is important to perform regular partial water changes in your aquarium to remove the old water and add new water that will be at the normal pH again.
How to test a rock in an aquarium?
Another means of testing an unknown rock is to fill a bucket with water from the water source you plan to use. Then test and record the pH, hardness, nitrate and phosphate. Place the rock in the bucket and let it soak for a week, then test the water again . If there are no changes, the rocks are not likely to cause a problem in your aquarium. If the parameters change considerably, we'd advise against using the rock in question in your aquarium.
How to tell if a rock is calcareous?
If you don't want to give up on the rocks you have, you should determine what they're composed of. Test the composition of your rock by putting a few drops of ordinary white vinegar on it. If the vinegar foams, the rock is calcareous and this will affect the hardness and pH of the water. Limestone is probably the most frequently encountered calcareous rock, followed closely by marble.

Limestone is probably the most frequently encountered calcareous rock, followed closely by marble. Another means of testing an unknown rock is to fill a bucket with water from the water source you plan to use. Then test and record the pH, hardness, nitrate and phosphate.
Does tap water have calcium?
Your local tap water may also be naturally hard (containing calcium and magnesium) and alkaline (containing carbonate), which adds further to the high pH. We'd definitely recommend testing the rock to see if it contains calcium carbonate and if there is any doubt, remove it entirely. If the tank pH stabilizes, you've found the culprit.
Is pH bad for fish?
Changes in pH are stressful—if not lethal—to your fish. Furthermore, sudden changes in pH can damage the beneficial bacterial colonies that eliminate wastes in your aquarium. In other words, keeping the pH at a steady state is just as important as the actual pH value itself.
Can pH be altered?
Altering pH. Although pH can be altered, we don't advise attempting to make major changes in the pH of your local water. It is very difficult to keep the pH stable over time, and you may be faced with an even more dangerous situation as a result: fluctuating pH. Changes in pH are stressful—if not lethal—to your fish.
