First I would love to see some tank pictures of people who run Kessil's ONLY and have tanks 75 gallons or more with SPS success......I just keep going back and forth from radions to kessil's and everytime I see a Kessil tank with SPS it is on small cubes or nano tanks....I have a 180 mixed reef with a lot of SPS now and I just want to make sure I spend the money wisely! haha .....One of the cons that are scaring me away from Kessil's is the "shadowing" of SPS....So that got me thinking....Would 4 Kessil's fix that issue?? I mean 4 Kessil's would STILL be cheaper than me buying 3 radion gen 3's....I know a lot of people have opinions on what light they think works or not for SPS, but a lot of times it could be a lot other issues than just the lighting....
