First off, let me say this is my first time maintaining a pool...I moved into this house in November, after it had already been winterized and covered.
I know from the pool store that they'd been using Baquacil, so one of the first things I did was pour approx 50 bottles of 8.3% bleach from Sam's Club into the pool over a period of a few days in April. It caused crazy green colors, lots of brown/amber goo at the bottom of the pool, two backwashes of the filter due to increased pressure, the whole nine yards. That all cleared up within a couple of days. I added a 3oz trichlor tab into the floater and took a sample to the pool store, who said everything checked out. The water has been crystal clear ever since.
In the ensuing week or so, I used Leslie's test strips daily, which never indicated any free chlorine at all. So I'd use poolmath and add about 96oz of 8.3% bleach daily to get a target FC of 5, which seemed about right. But every day the test strips would show 0 FC. Meanwhile the pool store consistently told me I had a level of 2ppm, which was good. But I decided I wanted more accurate tests, so I ordered the TF-100 test kit from TF test kits.
I found at this point that my FC was dropping to 0 very quickly after adding obscene amounts of chlorine. The amounts got more and more obscene. But CC is almost always around 0.5 or less.
At this point I'm trying to SLAM the pool, but I can barely get my FC to shock level for more than about 30 minutes at a time, even with very frequent addition of loads of chlorine. I've suspected my test kits, but the test strips, Taylor K-1000, and FAS-DPD tests all agree with one another. And I've also suspected my chlorine, but I've now bought 8.3% bleach from Sam's, 8.3% bleach from Wal-Mart, and 12.5% chlorine from Menards, and they all essentially behave the same way.
Here's my monster spreadsheet of what I've added and what my tests have shown: Pool numbers - Google Sheets
Anyone have any idea what's going on? Also, what's a safe FC level? I'm getting sick of dealing with the pool 20 times a day and would love to just throw 20 gallons of 12.5% chlorine in the &#$&ing thing at this point. Thanks.
