Dispensing Kalk

I am using kalk in my ro water to control ph. I have a large reservoir of RO that feeds into a kalk reactor. Top off is controlled with a coralife float valve.

I am having an issue where my float valve gets "kalkcified" in about 3-4 days and then RO no longer gets dispensed and neither thats the KALK Which I really need for PH control. The valve works fine If I bypass the KALK reactor.

I thought of using float switches and a valve instead, to could control the RO water into the reactor but the idea of using electronics as the only method is not very appealing. I also thought that if i could find a float valve that the dispensing part is inside the water then the kalk would no longer be an issue but I couldent find any.

Does anyone have a fool proof method to do it?
 
One comment and one question.
I have not heard any foolproof methods that is why I dose by hand two part.
What method do you use to control PH with your top off water? Would a controller work? Opps two questions.

I have an APEX. I have a PH probe in my tank and one in my calcium reactor. I dont have a problem with PH going high but as a backup to the float switch I have a solenoid valve in the RO side of the KALK reactor that will shut it of if ph goes over 8.5. As it is my PH is rarely over 8.

I add topoff water through a kalk reactor and I use a couple of float switches, the older "ReefGeek" topoff controller, and two solenoids (so there's redundancy). I agree that nothing's foolproof, it all needs to be checked tregularly.
 
Yet another method here. Sorry - I know i'm not helping. :p

I use a Tunze ATO (osmolator) hooked into a PM Kalk Reactor.

The sensor triggers the tunze to add RODI water. Instead of adding it direct to the sump - i've set it so that it goes into the PM kalk reactor. The reactor then deposits kalk into the tank.

For extra security - i put in two in-line valves to prevent any kalk from backflowing into the tunze pump.

You could bypass the reactor alltogether and put the powder directly into the RODI container -as I have seen a few people do here - but it will definitely reduce the viability of the pump life.

Hawkeye are these two valves check valves or solenoid valves?

For some reason I feel better about using a mecanical solution as opposed to the electronic one, but if I can find a better solution then I will go the electronic route
