    Added 121 oz 8.25 bleach to the pool at sundown. Just checked cl. I'm getting 2 or a little more FC and 5 CC. My pH is as I suspected, probably astronomical. I added 4 drops of the red stuff instead of 5, so it should have shown a lower pH than actual. Still LOOKED like 8.2. I gave it another jug of bleach.

    I guess the plan is go get the CYA tomorrow after I confirm my theory that FC will be zero and CC will be who knows where. Stick some in the pool to get the pH to a measurable point. If I understand correctly, the CYA actually inhibits the effectiveness of the chlorine so it is desirable to keep CYA low til the pool is stable overnight.

    With which test kit are you testing?

    We currently have a "Pool Shop basic 5 test kit" from Home Depot. It is the drops but reads only to 5ppm chlorine. It says FC is what you see between 2 and 3 seconds and CC is >2 minutes. I'm going to wally world today to get the HTH kit so I can monitor CYA levels.

    We got about 1-1/2" of rain last night and this morning the pH showed 7 - 7.2??? Can rain bring pH down that much? FC was in the 2-3 range. It's supposed to be cloudy today, should I dump another jug or wait til evening.

    Rain can have a low pH; whether it can lower the pH in your pool depends on the buffer level (total alkalinity). it's also possible the rain has not mixed with the rest of the pool. I'd wait & retest before trying to adjust the pH

    I assume this is NOT the kind of DE to use as a filter aid.

    Good assumption. There are different grades, and I have no idea if that one would be OK or not. Some grades definitely would NOT be OK.

    No more green! Kept FC between 5 and 15 for little over 24 hrs. Checked it every hour or so, when it got close to 5 (max for my kit), I'd brush the whole pool and dump half a jug of bleach which should have jacked the FC to around 15. The pool is cloudy blue now, as I expected. I got this
    http://www.walmart.com/ip/HTH-D.E-Fi...10-lb/20434370 (the picture is wrong, description is correct) and put 1/4 cup in my filter. Many of the local Walmarts stock it. Had to backflush after about 30 minutes. About 1/8 cup is seems to be plenty for my filter. After I get the water cleared up, I'll add CYA til it gets to about 40 and we'll be set.

    Thanks a ZILLION!
