Fertilizer dosing calculation help
Hey everybody, I have been using thrive + since I set up my 20 gallon high tech tank and its now to the point where I have to put about 5 pumps per day to maintain a nitrate reading of above 5 ppm so I now want to switch over to Mixing my own ferts for a more cost-effective and accurate dosing. I bought the PPS pro kit from green leaf aquariums and on the 500 ml bottle it tells you how much of each nutrient to mix in. I then after mixing the ferts as prescribed on the bottle I put those numbers into rotala butterfly and it seems that if I were to dose the recommended amount of the liquid I just mixed that I would be much less than the pps pro range as shown on rotala butterfly. For example, the macros bottle says to add 32.6 grams of KN03 to the 500ml bottle and add 1 ml per 20 gallons, and when I put that in to rotala butterfly it says I would be adding 1 ppm of NO3 per 2 ml dose and it says the pps pro range is between 5-10 ppm of NO3. And if i calculate for 5 pumps of thrive + which i am currently putting into the tank daily rotala butterfly says I'm adding 17.5 ppm of NO3. So I don't know if Im using the calculator wrong or what, but could someone please double check my calculations and help me figure out how much of each compound I should be using. Thanks
