Here's a little background first. I've been having good success with acropora so far. I have a 3ft red sea tank with 50% lps and 50% sps. I started with frags. Back in July 2022 . I have 2 xr15 g5 lights and I just added a 3rd xr15 g6 . A couple weeks back I started getting a little bit of dinos on the sand bed. So I lowered the light intensity a little bit and cut back on the reef roids and aminos. Now I added the 3rd xr15g6 this weekend and I'm noticing color loss. My bill Murray loss the red it had. The wwc Heartbreaker lost its red. My parameters are alk 8.5 cal 450 mag 1400 nitrates 9.5 phosphate 0.05 . Those numbers haven't changed in months. The lighting has with the addition of the 3rd xr15 g6. I don't know I'd running two g5s and a g6 is a bad idea or not. I got a par meter from my lfs . The acropora are still getting around 350 par like they always did. I run a modified lps soft program in mobius with higher whites And lower greens and reds. I keep my light intensity about 70% anything more than that I start to get dynoflaglates. Keeping a mixed reef is difficult because it's finding a balance for the lps as well as the sps. I still get high par numbers on the sanded where my acans are . It's taken alot of acclamation mode to get the lps used to higher light. My question is would the addition of that g6 cause color loss. Or is it more that I stopped the aminos and reef roids a couple weeks earlier?
