Fussion 700 Air Pump is a very quiet pump; it puts out lots of air, and is adjustable down to a very low flow. It has two outlets which can power one or two HOG.5 units, or you can combine them into one outlet (using the included T fitting that we put in) to power one HOG1 or HOG1x. You can use the two outlets to power one SURF2, which has two air inlets. Or get two pumps to power one SURF4 which has four air inlets.
In addition to the warranty from JW Pet, we at Santa Monica Filtration will warranty the pump for 90 days. However you must ship it to us first, before we ship a replacement to you. You will then also be refunded for shipping costs back to us.
