Which liquid chlorine?

[firstpool2020]

So I do not trust my pool store after the floccing incident.

I am currently using bags of Clorox to shock my pool but I have heard that liquid chlorine is better. Pool store says they sell cases of 4 for $21.99 but do I need to be looking for a specific concentration?

Any concentration works. Plug % into pool math and will calculate for what you have.
Walmart usually has pool essentials for less than $4 a gallon. 10% solution.

Typically you look for the concentration (~6% is bleach, pool stores will usually have 10-12% liquid chlorine) and the date it was produced since bleach/liquid chlorine can lose its potency quickly. That price is not bad, but you can usually get it cheaper at Walmart, Lowes, Home Depot, hardware stores, etc.

Every market is different, but $22 seems a little high to me. I pay $16 a case at the local mom & pop PS for 12.5% LC. Menards or similar usually has it as well for $13-15 a case, but it a longer drive to Menards...and it's Menards.
