I have a 46gallon tank that has been up and running for about two years. I was running a cascade 1200 on it until it started leaking, so I had to go with my bio wheel fliters til I could get the money together to purchase a new canister filter. I did not have any media for them so I placed the blue and white filter pads in them. The water has been cloudy every since. About one month ago I installed a CF-300 canister filter with new media had no used media. Did water test a couple of days ago and everything shows 0 except ph which is 7, I use the API Liquid test kit just recently bought a new one. I also do a 50% water change weekly which has not helped with the couldiness. Heavly planted dosing 4ml daily of a macro and micro fert package. I was informed from another person that it could be that I do not have enough nitrorigin in the tank with the nitrates being at 0. Was suggested that I add more nitrogin. With my ferts being a complete mix I do not know how to add more nitrogin. Ferts were purchased at AquariumFerilizer.com the micro and macro mix called MMN formula and contains the following 1 part KNO3, 1 part K2SO4, 1 part MgSO4, and 1 part CSM+B. Which I mix 1/4 cup of ferts to two cups water then I keep it in the fridge. I see new plant growth daily.
