The Litermeter can dose I believe up to 30 gallons per day. It takes the programmed total desired amount and divides that into 150 portions within a 24hr. period. The two additional pumps I mentioned earlier are for this purpose. One pump takes water from my sump and dumps it down the drain. The other pump takes the new premixed water and returns it into the sump.
All this is done in series. So as it takes one of the divided portions out with pump B it then moves on to pump C. All the while pump A (the actual Litermeter) is used for Kalk / evaporation top off. It sounds like a lot of work but it is as simple as turning on pump B & C and walk away … turn them off 24 hours later. The key is that my storage container for salt water mixing is 35 gallons. That said if I ever forgot to turn the pumps off I am only going to do a 35 gallon water change in about a true 200 gallons of water.
