i have run a 27 gal fishtank we used power heads for the undergravel filter. it circlates the water and adds air like a buble stone it has a deflecter but as i was setting the tank up and was getting it ready to proof i saw i could get the entire tank full of micro bubble it kinda look liked 7-up could a person use that type setup to mix and airate there nutes
spankey Reviewed by spankey on . Air Pump vs Water Pump I believe that using diaphram air pumps to oxygenate res water may not be the best way to go. This opinion is based on many years of experience in setting up and maintaining reef aquariums and researching techical information relative to the health of delicate corals. As I understand the air/water exchange principles, the actual gas exchange takes place at the surface where the air and water come in contact. The agitation of the water causes an incease in the volume of oxygen in the water. Rating: 5
