Non-Stabilized Powdered Shock

[SirSwimAlot]

What is the verdict on this?
I've been using it to close (Leslie's brand) and it is so much easier than 20 bottles of liquid chlorine every few weeks.

Is it as good as liquid if it doesn't include stabilizer? It is so much easier to stock up on and carry around, but it is more difficult to spread in the pool and I won't be able to use a Stenner pump which I planned on adding.

If someone is using a powder, got a recommendation I can get off Amazon or for a better price than Leslie's?

There are only two types of powdered chlorine: calcium hypochlorite and lithium hypochlorite. Cal-hypo is fine but your CH level will rise at about 10 ppm/week based on the amount of chlorine you say you use. Li-hypo is extremely expensive compared to any other options and not as easy to come by, but does not add CYA or calcium to your pool.

Nothing beats liquid on price and purity; meaning that it adds nothing but chlorine and salt. Everything solid adds chlorine, salt, and something else that binds it in to a solid form.

Based on where you live, cal-hypo should be a viable chlorination method. Just keep an eye on your CH levels and be sure to use seasonal draining and winter snow/spring rains to your advantage to get calcium-free water into your pool. Cal-hypo can be predissolved in a bucket and then poured in front of a fast moving return. Just be sure to not let cal-hypo powder sit on the liner as that can bleach it out.
