What fish do you have in your tank? Tank dimensions and lighting? Any plants? CO2 or fertilizers? How often do you perform water changes and at what %? I'm sure your water parameters are fine but post from your latest test anyway just so it can be eliminated. How many hours lighting does the tank get in a day. Does the tank get any direct sunlight?rollin75 said:Is red algae ok? It is red and fuzzy. Please let me know. I also have been having fish dying lately without any known causes does anyone have any ideas? My water parameters are perfect and the tank has been running for 2+ years. Please help.
What exactly is everything? What are your ammonia, nitrite, nitrate, pH, and KH levels?the parameters measure 0 for everything
