Ok, that all sounds reasonable... but if the problem is no stabilizer then shouldn't I add some? Or is it the fact we don't know for sure and adding at this point might be a bad idea?

I do have a taylor deluxe testing kit that has CL, PH, TA etc tests so I can test as you suggest... but a question... why do I want to raise the PH? Right now it's at 7.2 which I thought was where you wanted it?

I'm testing water today and I will do as you suggest above and will report back

thanks for the help
