I am having a problem with algae. Not green algae, it is mostly this red fuzzy algae. now, i know this screams in balance to everyone the question is what. I have made sure its not over feeding so i checked that off. I can only think of 3 things as the possibility. Lately pwc have been hard and honestly i have been behind too 1 or 2 times a month. Now the tank is pretty lightly stocked so it hasent been a huge deal since it is a 75g. The other 1 is i have a pretty high end light (2 t5ho) and i am not dosing or using co2. The other thing is i have been staying up late alot which means the tank havent been going off tell midnight to one in the morning. That is more then a 12 hour day of light. Now, 2 of these i can fix but i want to make sure its not the light. Thoughts?
