A quick Google search found that a ph=14 is equvalent to drain cleaner, so I kinda doubt you had a ph in the 20s! Man, it's been a long time since I had chemistry...

ok, into day 6 and here is an update. Still trying to keep the FC at 15ppm, and I'm using less Clorax. The pool is considerably clearer, but still has a green tinge. You can see the bottom throughout the pool (even in the deep end). I did some chemical tests before I left for work (DPD test/dilluted 2:1 for the FC):
FC: 12 (added 1.5gal of Clorax)
Ph: 7.5
TA: 170-180
That's all I tested.
On my way to work, I stopped by the pool store to test my accuracy. Their readings:
ph: 8.2
TA: 200
CH: 50
CYA: 10
They said they couldn't test for FC (huh?) but said my clorine levels were high (4+). I asked the guy what that stood for and he couldn't tell me (i.e. CC/TC/FC). Needless to say, I was surprised about that along with the difference in readings.
What's my next step....? Still Bleach and when to add additional chemicals. Should I try to lower the Ph?
Thanks and I hope my posts are helping others going through this ordeal!!
If you're using less Clorox and your pool is improving, those are very good signs! Stay with it, you'll get there. I would trust your pH readings over the test store's, and at 7.5 it is fine. You can lower it if you want, but I wouldn't bother.

The pool store told you the pH was in the 20s????????? That is completely off the scale AND then they told you the chlorine was locked because the water was too acidic??!?!?!?!? I think that person needs to go back to Chem 101 since the higher the pH the more BASIC the solution. Gotta love pool store expertise. Dude, if you go back for a test and that same guy is working I would just leave and save yourself the 15 minutes.

Hi Rev,
I've been away for a couple of days and just caught myself up on your conversion to chlorine. Would you say your water is crystal clear, but just still a bit green rather than blue? The reason I ask is because at the end of mine I was concerned that I didn't see the carribean blue color but when I had a pool inspection Thursday morning for the sale of my house I asked the guy about it. He reminded me that the perceived color of the pool is determined largely by color of the container it's in. He said that my pool looks great. I also did a search to see if I could find some info on the issue and one site referred to a more "classic" color which is what mine is.
Are you still cleaning anything out of the sock on your skimmer or has all that cleared up?
I just have to add, at the hotel we stayed at in San Diego Thursday night the pool water was the same shade of green as mine, but cloudy. I felt very smug.
Hope some of this helps,
Deborah
