Greetings - I have a sumpless ATO that draws from a 5 gallon reservoir of fresh water. I am trying to determine if I can add ca/kh/mg supplements separately to the reservoir so when my tank gets topped off, it is dosing it with the supplements. I have a 55 gallon tank and right now I top it off with about 2 gallons per day, but in the cooler months, it would probably only need 1/2 to 1 gallon topped off daily. Appreciate any guidance!
