I have fairly stable set up with moderate or fair SPS growth. The rocks are cured in tank BRS Pukani. The refugium has original rocks from previous set up. They are a hue of tinted geen with little coraline. The back panel and front glass will grow coraline however.
I have read in one of Julian Sprung's books that green rocks is a sign of under saturated calcium. Levels are alkalinity 140ppm, magnesium 1350 ppm, and calcium at 380.It is a low(er) nutrient system with undetectable nitrate by salifert and 0.03 phosphate by Hanna LR meter.
Lighting is 2 - 250 DE MH 14K - same bulb that Icecap rebranded. Not for discussion!, and 2 T5's over a 151 custom tank 4' by 28" x 28". I use GFO, but no carbon, and water changes with Tropic Marin. I did uses VSV mix for algae in past. No additives currently but food. Chateo growth in refugium is very slow lately.
Here is what I may consider to slowly favor a display with purple rocks.
1) use radiums 250K bulbs or lower output Reeflux 12K's. Read they prefer lower light.
2) Uses liter meter remote pump to at some kalk every hour by Neptune controller, knowing kalk growth helps coraline.
3) Buy seed plugs of corallne from IPSF.
4) skim dryer.
Any thoughts would be appreciated.
Thanks-
