My son turned his reef tank over to me after he moved out. It's a 55 gallon display tank with a 25 gallon sump. I need advice on what the proper lighting should be - intensity, how long to keep them on, etc. The lights I have aren't name brand. One has dual metal halide bulbs (150 watt each) and 8 sets of 2 blue LED lights. The other light I have is a dimmable white and/or blue LED. My tank has xenias, zoas, a few rose bulb tip anemones, leather coral, trumpets, rock flower, and a few other things.
About two months ago one of my kids adjusted the light settings and also fiddled with the light timer system. I didn't remember what the original settings/duration were to change them back. Since then, groups of my zoas have started closing and gradually fading away. My water parameters have been fine (see below). I can't detect any kinds of pests or any other problems that could be causing the problem with the zoas. So I assume that the change in lighting is the problem.
Can anyone tell me what light settings would be optimal based on the information above?
Thanks
