I got a good deal on these two used dosing pumps and have them both set up on timers. They're both feeding from old salt buckets with fresh water/calcium additive in one and fresh water/alkalinity additive in the other. I've got each timer currently on 20 hours per day and this is keeping the top up water level constant. The plan is to hook them to a float shutoff system before summer hols. I'm still playing around wih the concentration of the additives and adjusting as necessary.
