i have a pc 65watt 6700k over my 20 gallon refugium, and seems to be doing okay for my cheto algae. my display is a 90 gallon. seems to take a long time for the algae to grow inside the refugium. i do reverse daylight to help in co2 problems during the night. was wondering out there how big is your sump/display and the wattage of lights in your refugium and the effects in your refugium. thanks in advance
