Lovely corals and lovely colours.
I struggle to maintain pink colours. Other coral colours, including blues, greens, oranges and purples, seem to be fine. I do not think the light is an issue (8 X 39W ATI Power module with all ATI bulbs- 3 B+, 2 C+, 1 Actinic, 1 ABS, 1 P+).
Have you got any suggestions to improve pink coloration please? Note that I dose moderate amount of a Potassium supplement (Fauna Marin Ultra Easy K) every ten days. I dose it moderately because I am not able to test potassium at the moment. I am still waiting for Salifert to be on sale again (hopefully soon).
