I have been having issues dosing KNO3. I am having algae issues even with over 30ppm of CO2. I have pretty much determined the issue is with KN03. Here is the problem. I will do a 50% water change and dose 15ppm KNO3 and 1.5PPM of PO4. Just to verify this I will take measurements. The next day I will test and KNO3 will be nearly 0 and PO4 will be at or around 1ppm. It has been like this for a couple weeks now. It seems the only way I can keep KNO3 above 10 ppm is to dose about 15 PPM per day. I read the EI method and to be honest it kind of lost me. I would have to dose 20 ppm or more every other day to keep KNO3 at a decent level. which seems to me to be very excessive! Any suggestions?
