I have been using Chemi Pure Elite and I'm not seeing stupendous results. Should I go the extra bit and buy a Phosban reactor and added one of the several medias out there? If so what media do you recommend. I want corals soon before I run out of my dwindling Christmas money. I have a CUC, but there dumb and don't take care of my rocks well, just the sand. I need a good way to destroy the diatoms all over my glass and rocks for good!
