All right, here we go. I tried the t5s for a few months with my KessilA360x. Could not stand the t5s, lol. I know the health of the coral is what's primary but I couldn't take the Windex look and the colors not being represented properly. There was also the added heat, the lack of space to get into my tank without completely disassembling my light fixture, blah blah blah. Sold the t5 and now I'm stuck with just the kessil. Another reason I was okay with this loss of par is because I've decided to let go of the SPS and focus on LPS only. Having said that, I do still want an adequate amount of par from my LEDs. I'm considering going with either two noopsyche's or the 48-in reef breeders. I like the fact that the noopsyches will take up less real estate above my tank, but I've heard nothing but great things about the reef breeders and their warranty. Thoughts?
