Can't hold FC

[nepsa]

I think the FC issue has been resolved. I now have no ammonia. I used 10 gals of 6% bleach two night and 5 gals the third night. 33 hours later I have a FC 8.67 and TC 9.19 and combined .52

I'm I correct in thinking I need to stay with bleach rather than continue using the Poollife/Calcium Hypocholrite since my Calcium Hardness 475 and my Cyanuric Acid is 68?

Yes, you are correct. Your thinking is very good and on the right track.

I imagine it must sound like a broken record sometimes. Bleach, bleach, bleach. But it's the safest thing to add when chlorine is needed. It just adds chlorine, water and a minute amount of salt. Until new posters come back with water test results, liquid chlorine (bleach) is recommended for just that reason.

Then there's situations like yours. Liquid chlorine then becomes the only chlorine source that should be used. Looks like you done your homework.

Thanks so much for your help. By the way, I went to the pool store to get a test from them. They were clueless to the ammonia issue. When I started to share about the bleach, he tried to change the subject, but I did not let him off the hook.

Now that I have my problem corrected, I have the time to start reading the very value information your forum provides.
Until the next time---have a good one!
