I’m struggling to keep my zoas alive in my nuvo 20 since switching from a XR15 g4 (25% ab+) to XR30 g5 blue (75% ab+). I grew out a bunch of colonies from single polyps over 3 years but have lost nearly all of them since changing my lights to focus on SPS. They would bleach, close up and very slowly shrink away. My acros on the other hand have never looked better.
I’m down to my last 3 colonies and want to try to save them. I suspect the bottom of the tank gets 200-250+ PAR and I can’t dial it down without upsetting my acros.
Params:
Alk 8.3
Nitrate 5-10 (I dose potassium nitrate occasionally to bump it up)
Phosphate 0.07
Any ideas on how I can save these guys without having to setup another tank?
