Hi I am new to the saltwater world and had a few questions on setting up my lighting for my tank. I have a 75 gallon tank with a 15 gallon sump/refugium with a sea clone protein skimmer and a diy algae turf scrubber in the making. I have a T5 light set up with two settings one with white daylight and the other with blue actinic. How long should each be on for with conjunction of my lights for the refugium/scrubber?
My tank currently contains 3 damsels, a clown, a goby, a cleaner shrimp, and a pink tip anemone.
I have attached photos of my tank setup, sump and the stage the scrubber is currently in.
Any advice would be greatly appreciated
