Which kalkreactor to use?
 

Which kalkreactor should I buy? How about the Deltec KM500 Kalkwasser Stirrer? Do the mixers ever break or jam? How about the Precision Marine Kalkreactor KR620? It uses a pump instead of a slow mixer. Does the MaxiJet 400 blow the kalk around the reaction tube and into the sump if it is dripping while the pump is on?
