how much air for 150 gallon res?

how big a air pump would i need for 150 gallon res chilled 60F
right now i have a 35 watt 60L per min pump.

1 watt per gallon.1inch of air stone per gallon.You could probably get away with half that as cold as you have it. 75watt low 150watt recommended up to 2 watts per gallon extremely aggressive 300watts.Man that is a huge reservoir.

Good luck finding a reasonably priced pump that big. The largest I could find was 110l/m for 82 USD without getting into ridic prices.

Two of these should do the trick.
