Quick answer
Aquaculture aeration blowers are typically sized around 1-2 standard CFM of air per pound of fish biomass per hour under intensive stocking.
CFM = biomass (lb) x CFM per lb

Frequently asked questions
Does water temperature matter?
Yes — warmer water holds less dissolved oxygen, so hot conditions raise the aeration requirement.
Emergency backup?
Intensive systems should have a backup blower or generator, since fish kills can happen within hours of a power loss.
What do I need to enter into the Aquaculture Blower CFM Calculator?
Just 2 values: fish biomass, cfm per lb biomass. Every field starts with a realistic example, so you can change one number at a time and watch the result update instantly.
How does the Aquaculture Blower CFM Calculator work out the answer?
Aquaculture aeration blowers are typically sized around 1-2 standard CFM of air per pound of fish biomass per hour under intensive stocking. It applies the formula CFM = biomass (lb) x CFM per lb and shows the working so you can check each step by hand.
Is the Aquaculture Blower CFM Calculator free, and do I need an account?
It is completely free with no sign-up, no download and no usage limit. Everything is calculated in your browser, so the numbers you type never leave your device.
