it may sound silly but go for the biggest you can afford. you can never have to many bubbles. best of luck.Hi all. Surely would appreciate knowing this: What size air pump do I use for the 5 gallon DWC I'm putting together?
Thanks for any and all help.
same one i use, good pump and a good price. but you could probly use a 60 gallon aquarium air pump for just 1 res. if your going to do more then 1 5 gallon bucket or rubbermade get the AA but they are alot louder then the aquarium pumpsThis is the one I use, but I bought it from the local hydro store.
