my tank just recovered from a bout of brown hair algae, but the cause of it was excess iron. i was doing Seachem Flourish Trace and API Leaf Zone for extra iron (since seachem trace doesn't contain iron) and the brown hair algae just burst forth.
did my usual 50% water change last saturday and changed to Wonder-gro micro+ with no extra iron dosage, and my brown hair algae has disappeared. perhaps check the iron content in your Tropica fertilizers and see if you can reduce the dosage?
