I'm kind of stumped about what's going on with my water. I do a water change every Monday, feed every other day, run a protein skimmer and uv
sterilizer. Yesterday my water was crystal clear and today it has a greenish tint. I have a salicin tang pair of tomato clowns algae Blenny long spine urchin bt anemone and some hermits. Any ideas what's going on? The only thing I've done different recently was dose with an aquarium sludge remover to help get rid of some light organic debris on my sand bed.
