    Winterizing chemicals?

    SE Pennsylvania, 25kgal in-ground salt pool with mesh cover: I'm starting to get the catalogs with winterizing chemical specials. Most of them don't even say what is in the kits. Others say they include non-chlorine shock and "other chemicals to prevent algae, and control stain and scale."

    I don't have any metal fixtures other than the rim of a single 20-year-old underwater light, and I guess the stainless threads on return line plugs I'll be putting in. So I don't even know if I'm susceptible to stain or scale.

    Do I need anything other than an aglaecide? And which algaecides are best for winterizing?

    Are any kits a good idea, or are they all gimmicky?

    Mostly gimmicky. Take a look at this pool school article: http://www.troublefreepool.com/pool-...in_ground_pool

The SLAM process is not finished until: 1. CC < 0.5 ppm, 2. An OCLT < 1.0 ppm and, 3. The water is crystal clear.

    I disagree. Not just mostly gimmicky. All gimmicky.

    BBB chemicals don't change over the winter, just the targets.

    Yeah, I read that, which is why I'm wondering if I should do anything more than circulate Polyquat.

    Great time to be asking this question because Amazon has the good stuff for the cheapest price I have seen this year.

    http://www.amazon.com/gp/product/B0030B ... UTF8&psc=1

    I just bought some for closing this year and next as well. Not sure what the shelf life is or I might have bought more.

    Regards,

    Jay

    The KemTek is the correct stuff according to several ChemGeek postings and the label in the Amazon image.

    I am showing $13.33 delivered price for Prime Members.

    Follow that article, if you have any other questions post them here. By the way, I consider even the use of polyquat60 as optional and have not used is when winterizing my pool.

    I did the same as linen. Shock level only for me.

    Re: Winterizing chemicals?

    I didn't want to start a new thread so I'll piggyback on this one.

    If I'm using the BBB method, do I still need to get Anti-freeze for the pipes? If yes, can you recommend a particular brand or type? I'll likely order through Amazon unless the vendors on this site stock those items.

    Anything else I need to stock besides bleach/chlorine for the closing? Thanks!
