using my neptune controller with ph probe

going to bring air for the skimmer in from outside and bringing up alk and see what it does ill keep u posted thanks whatcaneyedo for the article

recent calibration on the probe?

yeah did it twice in the last few days and checked manually i will keep it posted as i bring in outside air bringing up alk slowly and ph was at 7.9 tonight

The quick answer is that your pH at that levels isn't too bad. It isn't optimum, but it is not likely to be causing any problems either.

The longer answer is to read the articles mentioned and think long/hard about how challenging it really is to move your pH to a higher level without causing serious harm to anything while you do it. It can be done, but trying to adjust pH is not something that is generally recommended.

yeah i wanna go slowly at it as well but when the ph got down to as low as 7.4 the other day it worried us bringing in outside air for the last hour has brought it up slowly well see how it goes
