Steven - 06/04/2010 I am using this pump to convert my corner soaking tub to a 'jetted tub.' The tub is 54" x 54". Folks were skeptical that this project would work at all. But I've installed the pump and drilled the holes through the sides of my fiberglass tub with a 1/2" wood bit, installed brass fittings (Hose Barb Adaptors A-96) available from Home Depot, and connected the vinyl tubing from the SL-65 to the brass fittings. It works great! My wife thinks I'm really clever. I've never heard of anyone doing this type of tub conversion. My only critical comment is that the six output plastic air distribution adaptor sent with the SL-65 was broken when it arrived. But Coralife (800-255-4527) was helpful enough to send me a replacement part at no charge. The SL-65 also includes a metal four output air distribution adaptor.
