Arch Chemicals HTH Sock It Shock-N-Swim Pool Shock - 18 x 1 Pound Bags

Grest bargain prices when u buy in bulk...ps for years I've sprinkled 1 bag of shock (using a colander or strainer) n my backyard & veggie gardens...This keeps most of the bugs away especially mesquitos & does not harm the grass or any vegetation!

I found these online and they are about %40 cheaper than buying them in the stores near me. It says to premix before throwing into your pool but I have a powerful jet that disperses it pretty quickly so I irresponsibly just throw it in front of the jet. I have not had any discoloration of my liner doing this as this stuff dissolves quickly and completely in like 5 minutes. I'd say I throw about 1 bag of these a week into my pool (more if we get substantial rain) and it keeps everything clean and stable.

This product is effective, and I like the bundle pricing. However, don't store it in a hot, moist environment or else the packaging will likely become brittle and crack apart. This happened to me before. This time I will store it in a more suitable location.

The best pool shock I've found. Sprinkle three a week into the pool (and add a few chlorine tabs in a floater) and I've kept our 28' above ground pool clear for many summers now

Great product, fast shipping and great prices.

Good supplier and Good product. Got it on time (fedex) and the price was right. Will reoder soon. Was cheaper than buying it locally. All bags were fresh and not retrieved from a warehouse after months of Hoarding. Pool is back to being blue again , the recent rains messed up the pH balance which encouraged Algae growth.

Good price for a season of shock.

Dissolves quickly in my vinyl in-ground pool. Costs a bit more than other brands, but should be easier on my liner.
