I have switched over to rodi
about a month ago with still high nitrates. Before i would stir up my sand bed once every two weeks. I had low nitrates up till now. My tank is about 5 months in and water parameters were perfect till up to till my nitrate problem. In one weeks time it went from 10ppm to a constant 40ppm. No livestock has died so im not sure where this steady nitrates are coming from.
Do you guys think my corals could be causing this. I got about over a dozen corals in my 30 gal
. Is there such a thing as overstocking corals?
