How Do You Lower CYA?

This has been discussed on the forum before and it is not recommended that this product be used.

Do not add any CYA remover. It will only make matters worse.

Waterbear is right about the evaporation and I should not have mentioned that. I also should have worded my response clearer by stating that by using bleach you are not adding anymore CYA. I was including the fact that you will have splash out and rainfall which dilutes concentration in your pool.

Watch out for the powder shock. Some are 4 in 1 shocks that have stuff in it your pool doesn't need. You can shock just as easily with liquid bleach.

Patience is the key with this issue. If you don't like your CYA level when you open next year, you can always drain a little more water away.

Another item that will lower your CYA is when you vacuum your pool, do it to waste. Then you are removing a small amount of CYA and when pool water is replenished either by hose or by rainfall it will not have any stabilizer in it.



Sorry for the confusion. Good Luck
