Opening to a cloudy pool, CYA gone

[Watermom]

Keep adding bleach. Sometimes people who close with a CYA level open to none. We see it all the time. It is caused by the biodegradation of the CYA. You can read more about it here:

Keep adding bleach. Test numerous times per day, the more often the better! Each time add more bleach. It may take a lot of bleach and several days, but eventually, the FC level will hold and the CC will diminish.

You also need to bring your pH up with some Borax. Also, use some baking soda to bring up your alk. Don't worry about adding CYA yet. You can do that after you get this issue taken care of first.

Run the pump 24/7 while you are working on this. Glad to see you back around the forum this year!

Thanks! I just read the article and it sounds like exactly what I have going on. I added the Borax and I'll bring up the alk with baking soda once the pH hits 7.5. Pump is running 24/7 and the pool cover comes off first thing tomorrow. I guess it's time to start looking for bleach sales!

I was planning to start running my chlorine generator to help keep the chlorine level up. But the article clearly states not to, so I definitely won't. I am curious as to why though.

Thanks again for your help. I'll post back with my progress.

You can seriously shorten your cell life by requiring your SWCG to keep up with this kind of chlorine demand, which is one reason why you use it to keep the chlorine level up under normal circumstances, but use bleach when trying to correct a problem.
