We moved in the last couple of months and since we moved, I have had an issue with the Nitrate levels in my planted tank. I know in the past to remove nitrates I have always done water changes. The problem I encounter now, is that my water supply is running at about 20ppm. I have found several products that will remove nitrates from the water, however all the products also state that they remove ammonia and nitrite. I do not wish to remove ammonia and nitrite from the tank as I already have biological filtration to accomplish that.
Does anyone have any suggestions for me? I am on a limited budget so RO
units are out of the question. I have an idea to maybe run some of the products on the water before putting it into my tank. Any help is appreciated.
