Spectacular Chemicals,

Pros: Tremendous Value with Quick Delivery
Cons: None
"I have been purchasing nearly all of my chemicals from In The Swim for about the past twelve swimming season. All of their chemicals arrive quickly, and all of them work well at a much lower price than the local pool stores.I have owned a pool for more than thirty years and wish I would have discovered In The Swim then. The everyday prices are phenomenal and when they have a special the deals are only better. From pool balancing to chlorine tablets, they keep me "In The Swim" all season. Now if they could only keep it sunny for my weekend parties, we would be all set !!!"

"Ordered Calcium hardness on Friday Afternoon and recieved on Saturday. About 2/3rds of the price of in store and I needed 75 pounds so good saving. I could not believe how fast I got this, will definitely look at In The Swim for future pool needs."

Easiest Product To Use,

Pros: Easy to use, directions right on the container, delivered right to your door
Cons: None
"We have well water and when we had it tested there was NO metals in it whatsoever. We have some of the best drinking water ever, but it wasn't fit to swim in, so the first thing we had to do was add the calcium hardness to it. We bought this container from In The Swim and it was delivered right to our door. We added it to the pool which was quick and easy, since the directions were right on the container and it did the job perfectly! We've only had to add it that one time. Thanks In The Swim!! Now I buy all of our pool products from you!!"
