I have a 72x30x25 220 gallon tank just about ready to be filled. I’m running a Vectra L2 with 2 3/4” locline returns with random flow generators. I also have 2 MP40s. I have the money to add 2 more mp40s or 1 MP60. What will work best for an SPS dominant mixed reef. Rock work will be down the middle of the tank with about 6” between rocks and glass on both sides. I’m not really interested in Gyre’s right now. I have 2 xf230s on my current 90 but maintenance is a pain.
