Getting back into the hobby after being out about 25 years! Don’t ask why. A lot has changed since then. Thinking of setting up a IM 15 g cube (15x15x15) with soft and lps. Was looking at the kessil a80 and the a160. Didn’t know which one would be better. I was thinking the 160 would have to much light spillage over the side of the tank. Also anyone have any experience with the reef casa halo light. It seems similar to the kessil. I like the the technology of the kessil. Any input would be greatly appreciated. Thanks
