I have been battling nitrates for a little over a month now (40 ppm). Even after doing a 30% water change in my small 36g the nitrates don't seem to drop. All other levels are perfect. I have 1 chromis, 1 six line wrasse, 1 cleaner shrimp, and a sand sifter SF. Any suggestions on lowering my nitrates a little?
