Excessive bleach consumption

[VOLDADDY]

OK, I added 5 jugs of bleach last night, and my FC is now 4 PPM. I am going to add 4 jugs to try and get my level to 12 PPM. I will test an hour after adding to see where I actually am and post results back. I think I lost about 8 PPM from last night to now.

Added 4 jugs of bleach @ 9:45, FC was 4, 21k IG oval vinyl pool. Should take me to 12 PPM. I am going to check in an hour or so-is this long enough for the bleach to circulate and mix?

mmm, should be.

At 11:10 I tested again and have 14 PPM FC. I was at 4 PPM and added 4 jugs of bleach to get me to 14, so 3 qts raise me 2.5 PPM. I will check in the morning before the sun starts bearing down on my pool and see if it holds steady overnight. Hopefully if I was fighting something, even though my CC has been 0, this will nuke it.

At 8 AM my FC was 8. There was absolutely no sun whatsoever on the pool that early so I can rule it out. I don't have any algae or dead things in my pool to consume that much chlorine. After I did my FC test I added the 5 drops of R-003 and it was a very pale color, more like cloudy. It didn't turn any shade of red. I added 1 drop of R-0871 and it cleared up, so I guess I do have .5 CC? I'm going to add 2 jugs of bleach now, which should bring me up to 13 on FC, and retest when I get home later tonight.

Do you currently have a high bather load? With just two people swimming in my pool about every other day, my CL demand goes up quite a bit, (especially after jumping in right after a lot of yard work)

Yes, all of a sudden my 7 year old daughter is the most popular kid around now that the pool is open. Plus, we have a lot of family and friends over on weekends for cookouts. However, yesterday, only 3 people swam for about an hour, maybe less, all day. I still lost 5 PPM overnight, no swimmers, no sun.

There is something working on taking hold in your pool. Bring your chlorine up to shock levels and keep it there until the chlorine holds overnight. You must be consistant. Everytime you let the chlorine drop down, the culprit is trying to take hold. The only way to get out of this pattern is to hold the pool at shock levels until they hold overnight. Try to test 3 x a day, if that isn't possible add more bleach to hold over till you test at least 2x a day - but make sure you test at night after the sun goes down, and before the sun gets on your pool, this way you will be able to tell when the chlorine is holding.

Kinda sounds to me like your cya isn't high enough for stabilization. I'd up that to about 50 and see if that helps. Are you sure you read the CYA test right?

day1,

He is around 50ppm CYA now.
