220 gallon mixed reef 12 years old. Lots of soft corals. We currently have 1 blenny. 1 mandarin dragon, 1 gabby, 2 yellow tangs, 1 Kole tang, 1 pigmy angel, 1tomini tang. Currently no top, but adding egg crate top. Wanting to add a group of clowns, anthias or wrasse. Had and liked 4 small clowns that only lived 2 years, and a pair of anthias that lived 4 years. No loss of fish the las 2 years. Thoughts? Also, when I add the egg creat, how much should I increase the light, 10%, or more? Thanks.
I increase my light to, 10%, or more?
