Is there a continuous PH controller / Monitor out there that doesnt cost hundreds of dollars? I am seeing the Milwaukee PH controller but the one feature I don't see is some sort of charting so that I can address variables that happen that I might not be aware of. I really dont want to spend $400 on a GHL starter kit (although I probably could have tried to get one cheap the other day!! ) nor do I want anything to do with Neptune and BRS. Any suggestions or advice would be appreciated.
Thanks
