When do you know your on the third stage of cycling (Nitrates)? Right now I have no ammonia and high nitrates and nirtrites. WIll it happen whenever the nitrites totally dissapear?
Plants offer another way of exporting nitrates but don't eliminate the need for water changes.Measure your nitrate in the tank. It should be below 40ppm nitrate at least. At best it should be at 10-20ppm.
NJDF, if this is true, then the EPA would not have placed a maximum nitrate content of 40 ppm for tap water.Originally posted by NJ Devils Fan
Uhh, tap water doesn't have nitrates. Since there is no ammonia in the water, there are no nitrates.
