I’m getting back into the hobby and will be purchasing a 30” deep 72” long 220 galling tank and am contemplating going with 3 or 4 of the 4th gen XR30W Pros. It will be a mixed tank with fish and SPS, LPS, softies running on an Apex. The coverage is advertised as 30”, but wanted to be sure three would be sufficient. I plan on a clam eventually and want to be able to support that as well. Anyone know if three of these will be sufficient?
