- 4.5 grams O2/100 pounds of fish/hour while resting and several times more oxygen while they are feeding and active. For example, a tank with 1,000 pounds of tilapia would consume 45 grams of O2/hour at resting, but maximum oxygen consumption may be at least three times higher (135 grams O2/hour) depending on water temperature, body weight and feeding rate. - [1]
- "cubic foot of air per minute for each 400 gallons of fish tank" - [2]. So for a 300 gallon tank that is less than 28 inches deep, look for an air pump that can deliver .75 cfm at 2 psi and you should be good.
- We have 1.8 cfm from our [3] pump - good for 800 gallons. Probably 2 of these are sufficient to power one of our Aquaponic Greenhouse 1 ponds.
