Air pumps

[stan]

Hi what size air pump for air stones should I use on a 240L tank thanks.

bigger the better your best bet would be the eheim 400.

all depends how many air stones you like to run :D
i run a 12000l/h for 18 tanks and i guess i can run 70+ sponge filter :D
its more a compressor than an air pump.....
for a couple of air stones a 200l/h should be easy
