Need some advice. I changed from 130W PC to 150W MH 20K on my 20G tall 3 days ago. As advised I put 3 layers of black screen to acclimate my corals. I have several Ricordia, Mushrooms, GSP, Zoanthids, and a Frogspawn. The Zoanthids look great. The Ricordia are kind of cupping up toward the light. The Frogspawn which is under the light is not opening as fully as before but the color is a much richer green and pink. My question is with the layers of screen am I getting enough light or too much?
