kalk via auto topoff

I want to start dripping kalk, however, I just don't have the space under the stand for another container. I currently have a single switch autotopoff system and would like to add kalk into the topoff bucket. I know it's a bad idea because if the switch gets stuck or skimmer goes nuts, I'll have a kalk overdose. So what i was thinking is to upgrade my autotopoff system to include an additional float switch for cutoff in case something goes wrong. Has anyone successfully dosed kalk this way. Any suggestions or comments would be greatly appreciated.

Sheep,

I plan to combine my kalk and ATO into one system. All you need is a container to hold the RO/DI, then you add your kalk to it, and use a peristaltic pump to dose it into your system. All you have to do is set the pump to add the exact amount that your system is evaporating. No float switches to fail.

sheep,

I used to have a float valve on my sump connected directly to my RO/DI unit with no issue for two years. I changed my auto topoff by using littermeter III because I heard horrific stories regarding malfunctions of float valves. My set up now consist of a reservoir of RODI containing kalkwasser mix and being pump to my sump with the LMIII. HTH.

Peristaltic pump does seem to be the safest method. Is there a specific pump that you can recommend?

A lot of people use the Liter Meter III, but it is pricey. Go to www.reefdosingpumps.com and look around there. Medical grade pumps (designed to run 24/7), brand new. He also has another website where he sells refurb'ed pumps for less. Let me look around and see if I can find it.

I am going with the Nautilus II as it will dose up to 4.5 gallons/day. I am evaporating around 2 - 3 so this will fit my needs nicely, and it is 1/2 the price of the Liter Meter III.
