knicks791;3607664; said:My oscar (5in) has hith too, but if my levels are perfect - ph 7.4, Ammonia 0 nitrate 0, do i still need to do more water changes? I do one 30-40 percent wc a week. I am about to treat it with Metronidazole. I feed homemade fish food (blended fish, carrots, multi vitamin and spinich) in the AM and Hikari gold in the pm. What else can I do? I can't take it anymore!!!!
Why is nitrate zero? This is strange. Very few cycled tanks have zero nitrate.
Have you checked the water from stray electricity which could be coming from a powerhead or heater?
