How much air for sponge filter??

[Cosabuena]

Hello. I have a 75 gallon tank. Bare bottom. 5 adult discus 5"+ and 30 cardinal tetras. I have a canister filter on it but I want to change to sponge since I do regular water changes anyway.

My problem is that I've never used these filter. And I understand that they work with air pump. What kind of ratings my air pump need to be to be enough for the sponge filter? How many sponges and what size I need for my tank?

Sponges and air pumps are all rated in gallon size of tank..

Find right sponge for tank.. find right air pump for tank.. connect both with air line..

Done
