My Aspirations are to have around 30-40 fish successfully living together! I have had 16 now, living together and healthy for the past 1.5 years. I'm hoping to continue to add more and top out at 30-40 in my 340 gallon, and have a lot of SPS and LPS corals. I'd say in 2 years of operation I am halfway there. I found a major issue of my phosphates being .55692 with and ICP test completed last weekend. So, finding a way to keep phosphates in check while increasing fish populations.
