But today we’ll take a closer look at the most important piece of pool fun: pool chemicals. Pool chemicals are important to keeping your pool water crystal clear and safe to swim in. From bromine to chlorine, pool shock to algaecides and pool clarifiers, In The Swim delivers what you want and what your pool needs.

Having the perfect mix of pool chemicals delivers that perfect crystal clear water we dream of on warm, sunny days. Pool chemicals such as chlorine, bromine and algaecide keep the pool water safe to use as well, killing harmful bacteria and other germs that can make a swimmer sick. Yes, the pool filter plays an important role in having clear water, but it only removes dirt and debris while recirculating harmful elements that could possibly lead to an illness. The chemicals make the water safer.

Perfectly clear, clean water that is safe to swim in is a balancing act of chemistry and art. However, with a little research, an understanding and proper testing the water for proper pool chemical balance, you will find it’s rather easy to have the ideal pool water throughout the swimming season.

Here are the best 8 In the Swim chemicals for your pool:


1. In The Swim 3 inch chlorine tablets - 25 LBS

Pool chlorine tablets dissolve into your pool water to kill algae, bacteria and other organic contaminants. Choosing the right swimming pool chlorine tablets is therefore a very important decision.

Maintaining the water chemistry of your swimming pool is possibly the most important aspect of pool care and can even save you money. Chlorine tablets are one of the key chemicals to maintaining your pool water, and 3 inch chlorine tablets are the most popular among long-time pool owners. 3 inch tablets are thicker than other pool chlorine tablets, allowing them to dissolve slower and protect your pool water for longer. Moreover, 3 inch chlorine tablets are the ideal size for your floaters or automatic feeders.

Sanitation and Disinfection is the most important aspect of good pool water chemistry, and powerful In The Swim 3 inch chlorine tablets are 90% available chlorine, and sun-stabilized, to make it easier to maintain any outdoor pool.


- In The Swim 3" chlorine tabs compare to Bio-guard, Sun, Guardex and Pace.

- One 3" Tablet of Trichlor delivers approximately 5.495 ppm of available chlorine and 3.27 ppm of Cyanuric acid into 10,000 gallons of water.

- Trichlor contains 54.2% by weight of the chlorine carrier molecule Cyanuric acid, each tablet of trichlor contains 4.336 oz of Cyanuric acid.

- Powerful 90% available stabilized chlorine. 99% Trichloro-S-Triazinetrione.

- Slow-dissolving, long-lasting chlorine works great in floating feeders or automatic chlorinator.

2. In The Swim Pool Shock Treatment

Use this Pool Shock to kill visible algae blooms and invisible bacteria, which could cause illness to swimmers. Your daily chlorination of the pool will kill most pathogenic bacteria, viruses and microbes, however to be sure that the water is sanitary, it is good practice to 'shock the pool', or super-chlorinate the pool every few weeks, to oxidize everything in the water, especially the invisible germs that may be harboring in the water.


- Powerful chlorine shock treatment is great for Spring start-up!

- Ideal for a quick chlorine boost when fast-action is needed.

3. In The Swim Ph Increaser

With powerful and effective results, this pH increaser is available at only half the price. Whenever the pH level goes under 7. 2 all you have to do is add pH increaser. This will reduce any acidity and fix water conditions.The pH level of your pool water is a vital element of your pool's overall water chemistry. PH measures how acidic or basic the water is on a scale of zero to 14, with the ideal pH for swimming pools falling in the range of 7. 2 to 7. 6. When the pH level of your pool falls below 7. 2, the water becomes acidic and can cause eye irritation, corrosion of metal pool equipment, dissipation of chlorine, etching of plaster walls and unsightly stains.To prevent low pH problems from occurring, keep an eye on the pH level of your pool and, whenever it drops below 7. 2, simply add pH increaser to raise the pH level into the 7. 4-7. 6 range. Your chlorine will be more stable, and other water balance parameters will too.
