One of my Oscars developed Popeye syndrome, and after having issues keeping the levels in his tank correct with the medicine in it - i moved him to a solo 20-gallon tank. He seems to be doing much better now.
But - the original tank still has one Oscar in it. The
nitrite levels are through the roof and I thought with regular water changes and time the Nitrites would drop and the color would go clear.
All the red tint from the medicine and the foam it produced is now gone. It's been about 2 weeks now but the Nitrite levels are ridiculously high.
What I'm doing now:
Day 1) 20% water changes, treating new water with Amquel
Day 2) Dose of "Cycle" with "More Nitrifiers"
Repeat every two day cycle.
The nitrites just won't drop significantly. Any suggestions??
