thanks for the answers I unfortunatly I'm not at that home right now to post the numbers I will get my neighbor to get them for me he is watching my pool. what is a good range for the ph? mine is runs around 7.4 to 7.6 . thanks Brad

It's not where you try and keep your pH that matters, it's how high it spikes before you lower it again.
