Free bioload calculator
Is your tank one hidden problem away from crashing?
A dead fish tucked behind a rock or an overfed tank can spike ammonia before you ever see cloudy water. Check your real bioload now, so you know before your tank does.

How much AquaChar®️ do you need to stabilize your pH?
By analyzing your Bioload, we gain insight into the living organisms in your tank. This helps us estimate the daily waste production and the required amount of AquaChar®️ to keep your tank stable and thriving.
What is bioload?
Bioload is the total amount of waste your tank's fish, invertebrates, and plants produce, mainly ammonia from waste and uneaten food. The more animals (and the bigger they are) in a given amount of water, the higher the bioload, and the harder your filtration has to work to keep that waste from building up and harming your livestock.
These results are estimates based on typical conditions. Livestock prices start at typical retail amounts; change them to what you paid. Replace AquaChar®️ sooner if you see cloudy water, odors, or rising ammonia or nitrite readings, and always follow the directions on your package.

Why AquaChar® Is Different
Conventional activated carbon adsorbs dissolved contaminants. AquaChar® is a proprietary, graphene-related filtration media made from recycled hardwood. It is engineered to do more than adsorb: it adds engineered surface chemistry and a home for beneficial bacteria.
Engineered structure
A proprietary forging process turns recycled hardwood into a highly porous, graphene-related matrix with surfaces that water, dissolved compounds and microorganisms can reach.
Engineered surface chemistry
Our B.A.M.S.™ surface treatment is designed to change how the material interacts with certain contaminants.
A home for beneficial bacteria
Its surfaces give beneficial bacteria a place to colonize and form biofilms, which supports biological filtration when conditions are right.
Independent lab results
Independent labs have measured E. coli and coliform removal, lead and mercury reduction, and methane adsorption in lab conditions. See the Science page for each result and how it was tested.
AquaChar® supports your filtration. It does not replace adequate tank volume, aeration, a cycled tank or routine water testing. Results depend on water chemistry, the contaminant and operating conditions.
AquaChar®️ Advanced Water Treatment, Inspired by Nature
AquaChar® is an engineered water treatment material. It works with natural physical, chemical, and biological processes to improve water quality, from aquariums to large scale environmental restoration. Its unique structure provides active surfaces for contaminant capture, water polishing, and beneficial biological activity. Backed by Science: Explore our testing and results.
