I have alot of years of experience with fw
tanks but only have my FOWLR
tank set up for a year and a half. I normally would wait till my bulb burnt out before changing unless it was a planted tank or the light just looked very dim. I have a Current USA Orbit PowerCompact Light. It has been a year and a half and seems to be just as bright. When should I replace the bulbs in the light? I also assume I don't have to replace the lunar lights.
