    anybody who can help of with setting up my pg controller. I have calibrated the probe to a ph of seven. Inserted the probe into the calcium reactor. Set the set option to a ph of 6.5. At the moment the ph in the chamber is 6.8 and the sol on the has bottle does not switch on. If i set the set ph to higher than the ph in the the chamber then it opens the value. Is it not working in reverse..
