Tank is about 2 months old and I have been doing the ole trusty 10% weekly WC/water testing. I was having g the usual new tank stuff, cloudy water, diatoms, and then all cleared up followed by some green algae on all surfaces exposed to light, underside of rocks is pearly white, and my nitrates fell off the map. I’ve been trying to bring them up with no such luck and the green algae is seems as though it’s getting thicker which to me indicates high nutrients, but still no nitrate. I’m going to turn lights off until Monday, tank is in a room that does receive natural light, is a two day no light period a good try?
