I am looking at the Matala m60 1/4 hp pump. I am also looking at the 9� disc diffusers from granger industries. This pump and diffusers are what I�m lookin at however that�s why I�m writing on this forum because i need some advice from the experts. I prefer a dyi systems to maybe save a few bucks but I also know I may be beter off buying a complete kit for a little more money. Please keep the questions and answers coming
