I have been using Kessil lighting over my reef since they came out with the A-150w's and then stepped up to the A-350w's and am currently have the A-360w's on a reefkeeper controller. I have been happy with the growth of lps and chalice corals, sps are growing....... Just not as fast. Anyone else using Kessil here? And how has your experience with them been? How long have you been using them?
