So my all together my 90 gallon saltwater system is going through the cycle and there is no ammonia or nitrite, but 40 ppm of nitrate. I did slightly less than 50% of a water change and a day later the results did not change. The salinity,pH and temp. are in check if that effects anything. Wondering if I gradually do smaller water changes in the future until the nitrates disappear or wait or....?
