I have a Deltec Kalkwasser stirrer, and frankly the design is pretty much the same as most Kalkwasser stirrers out there. I feed it with a dosing pump, about 200 ml per hour. The problem is that the water level rises inside the Kalkwasser reservoir and suddenly squirts out several ml at the time. Then the water level builds up again, squirts out a few ml, and so forth. I can't get the output to drip evenly. I tried putting a valve on the output, which works to some degree, but inevitably clogs. So, not happy about that. However, what works is to use one pump head to top up the reservoir with RODI, and a separate pump head to drip Kalkwasser into the sump. But I don't want to occupy two pump heads.
Any ideas how to get an even drip rate with one pump?
