You are welcome,like you said,no PH probe ,i have it now for 3 years and i am a very happy user of it,the past month my dose pump was broken ,that's it so far

Jawsee- thanks for the detail on your Calcium reactor- it seems quite different from standard Reactors no Ph probe and also easy to run! I may invest in one soon!
Has it ever given you any problems and how long have you used it for?
