Hello, I have been having for sometime 6 or 8 months this problem in my aquarium. It go from green to white cloudy water then it gets clear and them go back to either green or white water color. I see to have at the bottom some green algae sometime it see to be black. My tank is a 46 gallons and house it 10 Black long fin tetras, 4 red eyes tetra, 3 Platy and 4 serpae tetra. I have 2 java fern plants that are doing really good. I do not use anything for the plants. Filtration, I have 2 each 30 gallon aqua clear and one medium sponge filter from Co-op.
What can I do to get this under control?
