Is there anything out there that can be hooked up to an ATO using a pH monitor to prevent overdoses of kalkwasser..something that DOESN'T need to run thru a computer? We tried apex junior, but due to a lack of available ten year olds to set it up we were unsuccessful. Using kalk in the ATO worked great, until it didn't (thanks to user error). Still battling the side effects of a kalk overdose several days ago!
