How much air do I need

[captain1]

Lets say I needed enough air for 18 sites how large of an air pump would I need? I have a Alita AL 60 is that enough? or do I need more its like 2.9 psi But at a large volume. Any help would be great. 5 gallon buckets 6-8 air stones 1/4 tubing

40-80 lpm...

throw her in some buckets and find out. trial run time...

sounds as if it would be plenty, but don't take my word...

Thats what I was thinkin just wanted a heads up if I need more. Hoping to get away with one pump considering there like 200 bucks.
