I recently purchased a ACjr to control my CO2. Well I have it set to come on at a ph of 6.55 and off at a ph of 6.50. Well, it shut off at 6.50 like I set it, but it doesn't come on until a ph of 6.75. Anyone has an idea?
 
I have not hooked it up to the computer. but I just clear the memory and started over and I think it's working now. Thanks for your quick response.
