Hello everyone, I’m going on a long vacation with my wife for three weeks. I will have somebody feeding my tank, but I do not trust him to clean the glass with scratching it. Thinking of ways to reduce algae buildup, like reducing time of lights, or turning down the brightness. I don’t want to kill my corals, of course, but three weeks is a long time of algae buildup on acrylic. Any ideas?
