Hey guys I have been using: Seachem Reef Fusion 1 and 2 for keeping levels appropriate. It seems to be Ok, but just ok, I keep my Calcium at around 440 to 460 And the alkalinity at around 9 to 10 Is there something better out there that produces better results, Without robbing me blind? Would also be interested in what you all run your stuff at? If it matters, it’s a 45 Gal Bow front, all Hard corals mixed. Running a CPR 2R Bak Pak with a Lime wood air stone mod. A Two Lil fishes 150 reactor running Two Lil fishes synthetic ferric Oxide Daisy chained from the same pump into another 150 reactor running high end Carbon. Thanks for any input.
