40 to 50 ppm Nitrate. I did a water change in my 6.5 gallon betta tank. The betta that wont eat is safe, butt betta that will eat is 40 to 50 ppm. i did a 50 percent wc and the Nitrate still did not come down, so I did a 15 percent WC and that nitrate is still high. how did I get the Nitrate down?
And yes. I am using Spring Water!
