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.
