Product Description

In The Swim Di-Chlor
Di-Chlor Granular

In The Swim Sodium Di-Chlor Chlorine Granular

Swimming pool shock treatments are an essential aspect of spring pool opening but can also be used to give your pool a quick chlorine boost. Sodium Di-Chlor Chlorine Granular is a strong pool shock treatment which is used to kill algae and bacteria as well as other harmful water contaminants. It is also a great shock to use for Spring pool openings.

Use our Sodium Di-Chlor Chlorine Granular to kill visible algae blooms and invisible bacteria, which could cause illness to swimmers. Your daily chlorination of the pool will kill most bacteria and other contaminants. To be sure that the water is completely sanitary, it is best to super chlorinate by shocking the pool every few weeks. Doing this also allows you to oxidize everything in the water, especially the various contaminants that may exist in the water.

Essential to a Proper Maintenance Schedule

  • Powerful quick-dissolving chlorine shock treatment that is great for regular maintenance
  • 99% Sodium Dichloro-S-Triazinetrione Dihydrate (Sodium Di-Chlor) ; Minimum of 56% available chlorine
  • Does not contain calcium and is pH balanced
  • Dosage: 1 Pound per 10,000 gallons

Pool Care and Maintenance

It is important to maintain your pool/spa to keep it clean and healthy all year round. Good habits, such as cleaning your filter or emptying your skimmer basket, will ensure that your investment is protected for years to come. But most importantly, you and your family will be able to enjoy the swimming pool or spa each season.

Water Testing

Testing the water weekly or bi-weekly, depending on use and outside variables, helps keep your pool/spa water healthy. Utilizing a DPD or OTO reagent-based water test kit, test strips, or digital testing will help you monitor the pool or spa water chemistry.

Adjusting and Balancing

Adjusting and balancing your pool or spa water chemistry ensures that you will get the most out of the swimming season. The benefit of having good pH and Alkalinity levels is that it will increase the ability of your main sanitizer to kill bacteria. Balanced pool water chemistry will also reduce chemical and maintenance costs. Balanced pH and alkalinity help prevent corrosion and scale formation on the interior pool surface and surrounding equipment.

Sanitizing

Pool Fun and Safety

Green to Clean

Sanitizing

There are many different types of sanitizers used in various pool and spa environments. Clean and healthy water starts by establishing a proper residual chlorine level with shock or concentrated granular chlorine. The most common way to maintain a proper chlorine level is by using trichlor chlorine tablets in either a floater or chemical feeder. Applying these steps to your normal maintenance plan will ensure the elimination of non-living organic contaminants, bacteria, micro organisms, and algae making your water safe to enjoy.

Pool Fun and Safety

Now that the water is properly balanced and sanitized, it’s time to get in there and have some fun! We recommend enhancing your outdoor living environment with games, floats or loungers, toys, and accessories. Get creative!

Safety is of the utmost importance, and there are many ways to help make your pool/spa safer. Having a life ring buoy, a shepherd's hook, depth markers, coast guard-approved life preservers, door and water alarms and having your local aquatic environment safety regulations on-hand will ensure a fun and safe environment for your family.

Treatment

Even after all your preparation, sometimes life happens and your pool or spa can get away from you. In those moments, we need to start back from the beginning with testing of the water. Now that you have a clear idea of the current readings, your next steps will depend on the type of symptoms your water is presenting. This may include an issue such as algae (green, yellow, black, etc.), cloudiness, living organics, debris, and other water conditions.

5 Stars
Works great. Stronger than I thought.
I have an 18'x42" Coleman pool. I've been using this since I bought the pool. I supplement with 3" tablets in a floater. I was over chlorinating going by the instructions for "shocking." I've slowly dropped the amount using trial and error. Now I can keep the levels stable with 1-2 tablets in the floater and maybe 8oz or so of the granules as needed. Even through the crazy heat we've had in South Alabama this year. I think I can taper it off even more as the temperatures drop. Makes for keeping the pool crystal clear, super easy.
