Carl, Thank You....I have a good kit, not the one sold here (sold out, grrrrrrrr) but, one that was recommended as being quite alike, the Taylor. I had to add 8 drops to get the PH into range, so it appears I shall be hunting down the Tri-Chlor tabs this a.m. Muriatic Acid I shall get also, is there a rule of of thumb with regard to how much acid to use? I ask because I do not want to add too much at one time...

Thank You.
