Air pump for 2 gal tank

[shonzi]

can anyone tell me what the smallest available air pump is? i want to try & reduce the circulation in my tank. (the current pump is attached to an undergravel filter)

Are you talking circulation or surface disturbance. If you want less surface areation, such as when adding co2, use like a Rio 50 power head. They work much better on a UGF than a air pump anyway, and you can direct the output and you can turn the flow way down. You can also install a inline valve on your air line, but the UGF might not be as efficient.

Welcome!!!

For my sisters small tank I use the Rena Air 50, its really small and quiet, also I suggest you buy a control valve so you can increace/decreace the ammount of air going into the airstone or whatever it might be.

Good Luck
