I have been using this product as a supplemental pool shock for 16 years. I have lots of grand kids and like to keep my chlorine level at 3ppm. After heavy swim usage I shock with chlorine-free shock to sanitize with out raising the chlorine level. As a retired Pool Store employee I have recommended this type of shock many times to customers who have had high chlorine levels but needed additional water sanitation.

I have been using this product for years as I did not want to make the grandchildren wait to swim when they are visiting.
Excellent for unlocking the bound up chlorine in your pool. Product arrived quickly and in great shape. Will definitely buy this product again.

This is the best pool shock I've found! Just follow the directions and your pool will sparkle all summer long. I love the ease of ordering and the fast to my door delivery. I generally order enough for the summer as the box(es) fit well on the shelf in my poolhouse for easy access. The only qualm I have is the lack of easy opening as the bags require the use of scissors or some other sharp tool to open them. But the 1 pound size is handy to use and easy to handle.
I love In The Swim products and

We left our pool off for a week accidentally and here in the south that means algae!! We cleared most of it out, but it still needed super chlorination! This product worked perfectly!! We had sparkling pool water in 2 days! Thank you for making quality products at affordable prices!!! Would buy again and recommend!!
We have been very satified IN THE SWIM customers for 20 years, yes 20 years. We buy all our pool chemicals through your company. The Lithium Pool Shock is ESPECIALLY AWESOME as it dissolves very quickly, does not leave any residue and is vinyl liner friendly. I have & will continue to recommend all IN THE SWIM PRODUCTS to any & all that ask just where we shop for our pool chemicals as IN THE SWIM products keep our pool sparkling clear.

Keeps me from hiring poolman
I am a 57 year olf female and I got tired of the 2 1/2 gallon chlorine shock bottles from the pool store. This is a great source of unstablized chlorine. I use 2 bags to shock my 18 x 36 liner pool once per week and when my stablizer reading starts getting high from the 3 inch stablized chlorine tablets I put in my feeder then I use this as a source of unstablized chlorine and cut back on the tablets. The cost is a little high but the altermate is dumping a lot of water from the pool to reduce
... read more stailizer level. I never close my pool.

Does the job
I bought the hth Super-In-Swim to try it and I very pleased with it. It does a better job than what I had been using for several years. The cost is a little more but it is worth it. Here in Georgia, it does get very hot and humid so the chlorine does not remain in the water very long, however this stuff holds up a little longer.
