It took about 3-4 weeks for ammonia, then nitrates to drop close to 0. We added a bottle of copepods, BIO-spira, a damsel...

    Algae Identification

    Hey everyone. So recently I've had a bit of a algae outbreak on my new tank. I have never seen this algae before in my previous experience. I though at first it was just GHA, however it's a lot harder to get off and Is just in little clumps. Does anyone know what type of algae this is?
