Hi chalice experts, I want to get some advise on the chalice light intensity . Currently I'm switching to a hydra 26 for my nano tank. As I have different type of chalice (rainbow, pink bobbies, mummy eye ), I want to know what is the best par level for them. Before I kept them around 70 to 80 par, they are doing okay and kept their color but their color seems to fade a little (not as pop as I first get it) after they have been in the tank for a while. Is it because I'm using led not t5? What is the maximum par I can keep them as well?(because I have a mixed reef and the sps on top of the tank might need more light). Thank you!
