I'm trying to do the airstone modification to my Bak Pak. I bought a Coralife limewood airstone but am not sure how big of an air pump I need to drive the stone. What air pump are people using?
Not sure as to what size airpump is necessary... I would imaging that it wouldnt take anything too large, but you also wouldnt want one of the smaller ones out there. Do you have one laying around?
