Since the beginning of May I have been having issues keeping that demon, algae, at bay. I didn't realize that just adding a few pounds of "shock" was not going to solve the problem. The latest episode, or continuation of the very first, started last Friday, June 26 when I noticed that the pool was clear and I could see all the way to the bottom! Oh, wait, is that green at the bottom of my crystal clear pool?!? Yes, yes it was. So I threw in some shock and swept it. Still the same the next day. Repeat with the shock and sweeping, still the same on Sunday.
After lots of 'googling' I find TFP and tons of information. I had no idea what I had been doing. This is only the second summer with our little pool (15x4 AG Intex w/1000gph pump) and last summer I never had any issues. I hadn't even been using the test kit to its full potential. So, Sunday I put that test kit to good use, plugged in all the information on the pool calculator and realized I needed to put in some serious work!
Sunday's test results before starting SLAM: FC=4 (doubted this # due to green of pool, but had added lots of shock previous two days), CC=? (my kit does not test for this, it will give TC), PH=7.2, TA=70, CH=300, CYA=50. Sunday evening at 6pm I added the requisite amount of bleach (214oz of 8%) to shock for algae and swept pool. Tested again at 9:30pm, FC=18 and added 94oz of 8% bleach. Other #'s basically the same.
Monday morning at 7am I tested the water again, noting that the FC was down a lot, about 15ppm if the bleach did raise it according to calculator.

Thank you in advance for any help/insight! I apologize for the length of the thread, but I wanted to provide as much information as possible.

Monday's test results (7am):
- FC=13
- CC= ?
- PH= 7.4 (this # has risen)
- TA= 70
- CH= 300
- CYA= 50
Tuesday's test results (7am):
- FC= 18
- CC= ?
- PH= 8.2 (why does it keep rising???)
- TA= 80
- CH= 300
- CYA= 50
Today's test results (7am):
- FC=23
- CC= ?
- PH= 8.4
- TA=80
- CH= 300
- CYA= 50
- Should my PH be increasing just by adding bleach? No, I have not added anything other than bleach since Sunday. Before that I had some 3" pucks in a floater and had added 6+ pounds of shock (HTH brand) over a 2 day period. I took the floater out of the pool on Sunday.
- Will this amount of PH hurt my pool?
- Am I testing correctly? Yes, I have read the directions many, many times and pay attention to what I am doing when testing the water. Only the FC, PH and TA have changed when testing.
- Is there any other way to find the CC with my test kit? I have the Taylor K-2005.
- Is it normal for SLAMing to take several days even when testing and treating as often as I am? The water is no longer green, it is still cloudy. I also understand that the loss of FC means that the algae is still in there.
- I live in southeast Louisiana and it is very hot! We have also been having lots of rain off and on for past month or so.
