Ok but those light loving corals are not going to be very happy. I've never kept sps

and soft corals. Each year I replace the T5 lights and I do this all at once and because the intensity is stronger I start off with giving them a couple of hours each day unroll I reach the 8 hr lighting period. Their happy and growing and I've been doing this with pc
lighting and T5. To each his/ her own!
