Dosing (top off) units for Kalkwasser Reactors ??s

[SmknReefer]

Hello,
I have just recieved the Precision Marine kalkwasser reactor and would like to automate the process to have it dosing into the sump.

In general what are some opinions on the different dosing (topoff) units that will work best for this unit, is there any one unit that is worth the cash or has a good reputation?

Thanks for any help.

SpectraPure Litermeter III is what I use. Expensive but worth it. Quiet, compact, easily adjustable with digital readout. Had it now for I think about 2 years without any problems.

Try to find a used litermeter. I got mine for $100. Best thing I bought for my reef.
