I think your test kit is way off. Have you calibrated it? 11 grams of KNO3 would give you 32 ppm of NO3 in a 55 gallon tank and your tank wouldn't use that much in a week, much less 3 times a week. I think you're over complicating things. EI is dry dosing and it's as simple as can be. Read the Dosing Regime's sticky at the top of the forum and you'll see how simple and consider giving it a try. I use it and it works for me and a lot of other people.
