well i got a little defensive that i was overcrowding. I have to many fish in a 300 gallon rubbermaid and have been fighting the nitrite level. ammonia is 0 but i just can't get the nitrite down. I have the pond salted to .15 to to keep it ok. I encourage everyone to test all levels ammonia, nitrite and nitrates. if these are kept near 0 especially nitrates then your fish will thank you. I will move and sell some fish to get things back on track. the fish are healthy and doing fine but the nitrite is .25.
sorry for my over defensive again. I respect all your advice
