Hello. I have slime growing out of control in my planted tank. Last week I tried a blackout period of two consecutive 48 hour periods with a water change in between and it seemed to really help, but now it is back with a vengeance. I have removed some of the plants it was coating and added some fragments of elodea/anakaris. The sponge filters seem to be the most heavily affected part of the setup but slime is appearing everywhere. Ornaments, substrate and glass I can clean easily enough but the plants and the moss covered tank divider I can’t. How have you guys managed to clear it in your tanks?
