My tank is starting to get overrun by green hair algae. I think that it might possibly be rhizo, but I'm really not sure. Hopefully you all can help me out.
Specs: 29 gallon with 96 watts T5 ho light, 6500k bulbs, CO2 at about 30-40 ppm. No fertilizers except for the past two weeks. (I've been dosing KNO3 according to the MCI)
The algae started a few months back and seems to be steadily getting worse. I added a few amano shrimp, but not nearly enough to clear all of the algae. I would like to solve the underlying problem that is causing the algae, but if I can I'll add more shrimp and fish to eat the algae. I've been manually removing the algae with a toothbrush for the past month or so. It isn't too hard to remove, but it grows back very quickly. It seems to form large bundles in the open water and now it is forming on the glass and starting to get tangled up in the plants. It has a stringy texture, not slimy, it does not hold on to the plants too tightly, but it also does not break very easily.
2 weeks ago I started the MCI, specifically the generic KNO3 protocol as described in that thread. I started out dosing a 1/2 gram of KNO3 daily. (don't know if this makes any difference, but I mix up the dose in a small container first with water and then pour the mixture in the tank) 1st week went by with no positive results. Started the second week last Saturday and upped the dosing to 1 gram of KNO3 daily. I'm at the end of another week with no positive results, in fact, the algae actually looks a bit thicker and it seems to be growing back even faster than before. It has also started to grow pretty heavily on the glass and it is started to cover my HC along with other plants.
Does anyone know what kind of algae this is and how to get rid of it? Should I just continue the generic KNO3 protocol and up the dosing to 1.5 or 2 grams daily starting tomorrow? If anyone has any suggestions or ideas, please help me out. Thanks in advance.
