OK so I have a small amount of BGA developing in the corners of my tank. I am sure it bloomed because of my bogus NO3 test and my through the roof PO4, so I neglected to dose macros for several days, and wham! Moral of the story, do not stop NO3 dosing, and ignbore test kits! i also think I kind of overfeed. I have never had algae hair, thread, or any other type, so this is something I want to get a handle on before it becomes an issue. I will be doing a 3-4 day blackout. Can you guys help me with the procedure? Should I dose NPK before the blackout and forego fish feeding, or maybe peek in at night to feed? Your help would be appreciated.
