I had 5 over my 290g, mainly sps which is 82L x 30W x 28H and it was plenty of lightI am curious if someone can tell me the approximate spread of one of these. I have a 6ft 125 gallon, it’s relatively narrow and shallow, and I really like everything about these. I’ve looked all over the product info and can’t find a coverage suggestion. I’m thinking 3 minimum but 6 would be ideal lol. I’ve been growing hard corals for a long time with viparspectras but really want to upgrade and I refuse to buy radions lol.
