how to maintain chlorine in hot water

[archer636]

I have noticed if I keep the temperature at 91, the chlorine will dissipate several times faster than 89. Is there a way to maintain FC a little longer? I know CYA protects against sunlight- not sure about heat though.

That sounds odd. I have not seen that in my pool that reaches near 90F in the summer.

I assume your question is for your spa or pool?

My pool is 96 past few days. It's more reactive compared to 85 but nothing like "several times" fc consumption. 89 to 91 would hardly be noticeable so I suspect something else going on.

Maybe I exaggerated a little but I do feel the FC consumption goes up exponentially with temperature. I am talking about spa- so desired FC level is higher than pool.
There is no CC present, filter is clean, water is clear. I shocked a few weeks ago when I put in fresh water.
