I was really excited to get this light for one of my new builds. Just a little Red Sea nano I’m putting together to use as a frag tank. … The Radion is kinda weak par wise. No wonder the schedule puts it straight to 100%. I have a par reader and I Maybe 5 inches below water surface it’s hitting...

Hey all, I just purchased an a80 to light my fluval evo 13.5 tank. Was thinking of just for softies and maybe lps. Would adding another a80 down the road be sufficient for growing any LPs and some montipora? It’s hard to find par spread diagrams on these and I’m just curious what the par and...
