Kalkwasser and float valve

[dougdstecklein]

Does anyone use a float valve with a gravity fed auto top off system to dose Kalkwasser?
I am wondering if I will have issues with the float valve clogging.

I used to dose Seachem reef builder for alkalinity in my auto top off, which is a 2 gallon bucket that sits above my sump. It is gravity fed using a float valve. The only time I've had issues with it clogging is when I've allowed it to run dry.

Doug, how's using the Kalkwasser through your float valve working? I'm considering the same thing.

I tried, many years ago. Didn't get stuck on, like I feared, but it did clog to the point that it'd quit dripping. A peristaltic pump of some sort on a float switch is probably a safer bet. BRS's dosing pumps seem quite the deal to me.

I am using a float valve and gravity feed ATO system, and wouldn't have it any other way. I don't use Kalk any more, but I picked up a cheap (marine magic) 3 head programmable dosing pump for Calk and Alk. Works fine so far.

You can put a kalk reactor between your ATO reservoir and the sump. I use the reactor with a Tunze osmolator. Works great.
