First of all. Why are you dosing Kalk? Is your level low? Second, where is your level now? Third, how much is dosed in 5 minutes and how much is dosed in 10 minutes. Fourth, where does each of those dosing times take your level too?I got brs kalkwasser I would let it drip in for maybe 5-10 minutes once every few days but I haven't done it in about a week now. I feel as though a small gravel vac should be in order pretty soon
