I recently started dosing kalk via my ATO. I am dosing 1 tsp. per gallon. My aquarium evaporates about 3 gallons a day. My ATO reservoir holds 5 gallons. There is under a gallon that the pump cant get off the bottom of the reservoir. My ATO reservoir is automated (self-filling with RO water when it hits the low level) and refills itself roughly every other day. My question is about when to add the kalk mix. Should I add the dose for 3 gallons (evaporation rate) every day? Or should I add the dose for 5 gallons every other day when the water refills? The timing on the refill isn't like clockwork, so it seems like it would be better to add every day just in case I'm not home to dose after a refill. Will the super saturated kalk eventually become saturated? What do you think?
