Great products, April 22, 2009
By bigbobber from Waxahachie, Texas

Pros: works great, much cheaper than big box store
Cons: shock slow to dissolve, but I mix in bucket.

I always wait for free shipping and handling, then buy larger quantities."

clear water now, December 14, 2008
By clearwater from Liberty Hill, Texas

"Last summer was the first summer since I've had my pool that I have been able to keep it clear. I found out that if I use the pool shock once a week and do the algeside maintence schedule and keep chlorine at a good level it just stays clear. Before I wasn't consistent with my chemicels and it would get cloudy and green I was about to give my pool away. I found that wonderful floc stuff works great when your pool gets cloudy and green. Where I bought my pool chemical before i started buying from in the swim they didn't tell me about that floc stuff, but once i started being consistent with my chemicals I didn't even need that floc chemical. please forgive my spelling, and correct it if you will."

Simply the best and most convenient to use!, December 14, 2008
By Zoeey from Long Island, NY

Pros: Easy to use, next day delivery; and door service!
Cons: NOTHING!

"I order about 3 cases of this every season and it is so easy to use. No measuring; 1 1lb. package for every 10,000 gallons of water. I have used other brands from the local pool store and did not have the same results as I get with this shock. Will never ever run out of it again! Order on the phone or over the net and I have the next day or day after and they even deliver on SATURDAYS!

Oh and by the way.......customer service....simply the best when I have questions over the phone! 5 GOLD STARS for them!"

Does The Job, December 1, 2008
By wgcruise from Portland, OR

Pros: Inexpensive, effective
Cons: None

"My local pool store charges much more for a shock product that doesn't perform any better than In The Swim's version. I use it, along with the 3 inch chlorine tabs, to keep my pool algae free all summer long."

Pool Shock, December 1, 2008
By InTheTexas

Pros: Perfect size shock for my pool
Cons: None

"I'm done purchasing sub-standard chlorine and pool shock from regular stores. I use 1 dose of Intheswim's pool shock for my 10,000 gallon pool and I'm done. The quality of this shock is clear as my pool's water. Order in advance and stock up and you'll quickly see the value of this product."

By noblen from Middletown, NY

Excellent Product!, November 27, 2008
By SouthCarolina1 from Spartanburg, South Carolina

Pros: Fast disolving; non bleaching of vinyl liner
Cons: none

"I have used this product for many years, and find it to be very effective in algae prevention and sanitizing of the water. I particularly like that it does not have to be dissolved in water before adding it to the pool. My grandchildren have never complained about "stinging eyes" or a chlorine smell. The product is always delivered in one or two days after ordering."

"To Me, From Me"!, November 27, 2008
By POOL34056 from Decatur, IL

Pros: Excellent product, affordable, professional, reliable
Cons: Must mix well

"ATTENTION POOL FRIENDS: Make Your Life Easier on those beautiful hot and sunny days with this product! I can relax and get my tan on knowing that I can be confident that my pool shock is taking care of any problems lingering in my pool! In The Swim has been absolutely professional, timely in delivery and service, and the only supplier for me. And trust me I am super picky! All I have to do is place my order online and POOF it arrives at my door a day or two later. I am so all about delivery to my door! If you have a family, etc... and time is an issue, give yourself this "To Me, From Me" gift, climb on your raft, and make your life and pool maintainence super easy!"

June 30, 2008
By RonPags7

Pros: The Price!
Cons: The Water remains cloudyfor two days after

"When using" ITS" Pool shock, the following morning & for two days after the Water remains cloudy. I utilize clarifier the next day with the filter continually running. I did find out one time the alkalinity was low, once I increased the Alkalinity level the water amazing became clear. With no heavy rain this time & the water balanced, the pool still clouds up. I switch every other week with the non chlorine shock by "ITS" and that stuff is great! I am thinking about using a different brand or trying the Super pool shock by "ITS". Why is it the pool shock package suggests to "not" predisolve in water but on the website it suggests that you should predisolve?"

Effective, May 21, 2008
By lbianch from Southeast Mass

Pros: Value, Clears up a green pool fast
Cons: It didn't dance

"Had dark green pool water when I opened. Once the pH and alkalinity were ok, put in 4 lbs of this (24,000 gal) and it turned a light green. Another 2 lbs and it was clear. Can't beat it. Will definetly use this through the season on a weekly basis."
