Choosing the Best Chlorine Type for your Pool.

Based on composition, pool chlorines are of two types: stabilized and unstabilized. Stabilization simply means the addition of cyanuric acid to chlorine during formulation. This cyanuric acid (CYA) shields the chlorine molecules from the sun. It serves as a kind of sunscreen for chlorine molecules, stabilizing the chlorine.

Indoor pools are often not affected by sunlight and do not necessarily need stabilized chlorine. For outdoor pools, however, stabilized chlorines are best. Unstabilized chlorines are not protected from the sun’s UV rays, and chlorine molecules are easily lost. Using unstabilized chlorine in your outdoor pool means you’ll have to chlorinate very often.

Liquid chlorines are often unstabilized. In addition to that, it is not very easy to achieve uniform chlorination using liquid chlorines. This is because they are often poured directly into the pool. Specialized feeders are required to achieve uniform chlorination.

90% of chlorinating tablets are stabilized. They are fast becoming the preferred choice of pool sanitizers. This is not just because they are stabilized but also because they are safer and easier to handle. Chlorine tablets are of two sizes; 1-inch tablets and 3-inch tablets.

Why Choose the HTH 42037 Super 3” Chlorinating Tablets?

With the multiplicity of chlorine tablets available in stores, you might just be wondering what’s special about this brand. Let’s find out.

First, the HTH Super 3-inch is the first chlorinating tablet with a 4-in-1 formula. It doesn’t stop at sanitizing your pool and protecting chlorine molecules from sunlight, as most brands do. It goes further to prevent algae growth and clarifies the water.

With the HTH 42037, you do not need to carry out separate algae treatments often. It keeps your pool free from algae ensuring the water remains blue and clear.

It also gives great value for money. Not only is it very affordable, but its advanced formula also makes it possible to use just one tablet for 10,000 gallons of water. Plus, your pool stays chlorinated for one week. Saves cost and time. Great, right?

The downside to this product is that the tablets are not wrapped singly in the bucket. Because the tablets are fragile, they tend to crumble if not properly stored (particularly during transportation).

How to Use the HTH 42037 Super 3-inch Chlorinating Tablets?

Unlike liquid pool sanitizers, which are measured and poured directly into the pool, chlorine tablets are not be used directly. Using them directly leads to uneven distribution of chlorine and over-chlorination. This makes the pool unsuitable for use. It could also damage the pool surface.

Chlorine tablets are used in feeders, skimmers, or floaters. The simple steps for using the HTH super 3” chlorinating tablets are:

  1. Test the pH of your pool to ensure the water is balanced. Chlorine sanitizers do not work well when pH is too high or too low. pH range of 7.2 to 7.8 should be maintained.
  2. Ensure there are no residues of other chemicals or tablets in your floater or skimmer.
  3. Place the HTH super 3-inch tablets into your floater or skimmer basket.
  4. Place floater into your pool and allow to float for as long as it takes for the tablet to dissolve (usually two to three days).
  5. The pump should be kept running for at least 8 hours per day to ensure proper sanitization.

NB: Do not add any other chemical to your skimmer or floater while the tablet remains inside. Skimmers have to be used with the pump turned on to prevent acid build-up.

How Many Tablets Should I Use?

Typically, one HTH super 3″ tablet chlorinates a 10,000-gallon pool for one week. The size of your pool, therefore, determines your tablet usage.

For example, let’s say the size of your pool is 20,000 gallons. You’ll need two tablets of the HTH super 3-inch tablet to chlorinate your pool per week.

How Often Should I Chlorinate My Pool?

How often your pool needs chlorination depends on the number of users and frequency of use. Ideally, a normal family pool should be chlorinated at least once a week. In the case of high usage, though (e.g., pool parties), a pool will require chlorine treatment at least once in three days.


How Long does the HTH Super 3-inch Tablet Last?

It takes two to three days for a super 3” tablet to dissolve in a skimmer or floater. The free chlorine molecules released from the tablet into the pool can keep the pool chlorinated for up to a week.

In the case of heavy pool usage, a pool test should be carried out after use to determine the level of chlorine in the pool. The result of the test will determine if the pool needs chlorinating. Pools should also be tested after rainfall. For ideal swimming conditions, maintain a free chlorine level of 1 to 4PPM in your pool.

Asides from usage, there other factors that determine how long a super 3-inch tablet lasts in your pool. They include:

  1. Pool temperature: Chlorine tablets last longer in pools at cooler temperatures.
  2. How the tablets are added to the pool (floater, skimmer, feeder)
  3. Pump or feeder settings

In a Nutshell
