^ Yep. I really like TM Pro. I have never tired the new Bio stuff. With the way Pro Reef performed for me I dont think I will. As I said before I have used many salts but not all of them. Right now I am trying H2Ocean and so far I like it. I would still be using Pro Reef if I could find it locally and for under $100. I have used IO, RC, Coralife, IO/Oceanic mix, Pro Reef, HW Marine Mix Professional, HW Reefer and H2Ocean. The best IMO out of these is 1 Pro Reef 2 H2Ocean 3 HW Reefer and 4 RC when it is not a bad batch.
