When to add stabilizer (Fall vs. Spring)?

[MBMMPool]

Hey, guys-

My 18x36' pool is currently filling following a planned Vinyl Liner replacement. After a few days of cycling to check for leaks, the pool will be winterized (I live in Ohio- we are DONE swimming!). Pool has an automatic cover that will be closed until spring.

Question: Any benefit of adding/dissolving stabilizer NOW, or should I just wait until Spring? As the water will not be exposed to any sunlight over the winter, will the stabilizer help maintain chlorine level in any real way?

Thanks for your time & opinions.

I cannot see how it would do any good in a covered pool. However, algaecide might be advised. We need to hear from one of the northern folks about this.

It seems to me that cya would help like it does for indoor pools by moderating chlorine and keeping a reserve.

Wait until spring. Covered pool, new water, cold temps - minimal chlorine loss. Just my. 02.

There are numerous posts where chem geek posts about indoor pools and suggests that having some CYA in them is smart as it moderates the chlorine's affect on swimsuits (and I presume reduces impact to liners, and covers, etc) and provides a reserve. I don't see why over the winter that wouldn't be useful (other than the swimsuits part!) I'm not saying put a whole bunch in - 20-30ppm total should be sufficient.
