I dont do water changes so it is inevitable that I will have to dose potassium. I also use the red sea ABCD according to Alkalinity consumption it has potassium but apparently it is no where near enough. I am just a little curious about this math. I purchased potassion P and the product states 5grams/8oz stock solution and to dose it at a Maximum rate of 10ml/20gallons/day. However it also states that the solution will raise the potassium at a rate of 1.7ppm per 1 ml stock solution per gallon. So from that it appears that they are suggesting that the maximum rate of raising potassium with their product is .85ppm per day? which is probably less than my consumption rate. So should I try and calculate my daily consumption rate and then add that to the max dosing rate?
