After six weeks my 16 gal. Freshwater with fish tank is cycled. The parameters are ammonia and Nitrites 0. My concern is my Nitrates. There is barely a trace at 5.0 ppm. They were at 40 and my Nitrates were very high at one point. I PWC them down. Did I kill the good stuff. That seems sorta low. question two...how long before I can add new fish like an Ottocat. I presently have three Neon a tetras, three Zebra Danios, and One Hi-Fin Platy. how many more can I add. I had one Platy but she died three days after we brought her home. My Platy is lonely...she schools with the Danios.
