Hi everyone I would like to change out some of my pond water is it an 800 gallons with a bog an overflow at the back of the bog. My dilemma is in the past I have removed quarter of the water and put clean water in using prime to adjust it. It wasn't until I put this new 800 gallon pond in 2 years ago that I came across a problem my source water test it out for very high 5.0 nitrite. I resolved this at the time of the new Pond by dumping a whole bottle of Night Out 2 bacteria in and using Prime. It did resolve the problem I just don't want to have to do that every time I do a water change. My question is I have a filter on the end of my hose for chlorine and chloramines Etc the water still does test for high nitrite. I was thinking about slow dripping it at the one into the pond to the point of a slow overflow out the back of the bog would that change up water enough. If I drip it slow enough does it give the bacteria time enough to handle the nitrite coming into the pond?
