Serviceable, quiet powerhead By Jeff on 5/2/13Jeff would recommend this product to a friendI bought this powerhead for extra flow in my 18" cube coral quarantine tank. It has nearly silent operation and does its job well. I would encourage anyone looking for a small, inexpensive powerhead to give this product a try.
