Dealing with Pool Chemicals


The more pool owners know about pool water chemistry, the more they would recognize owning a Chlorine Genie is a wise choice.

There are several common methods used to try to keep the pool water safe, clear, comfortable, and ready to use  24/7.

  1. Liquid Chlorine
  2. Pills and tablets 
  3. HTH Granulated chlorine
  4. “Salt in the pool” type chlorine generators 
  5. Weekly pool service 

There are other supplemental products that aid in pool water sanitation, like Ozone, UV, Ionization etc. but the Board of Health does not recognize these products as the sole method for pool sanitation.

Each of the above  methods have their STRONG points and their WEAK points. 

We, at Chlorine Genie, have spent years developing a stand-alone system that enhances each method’s  STRONG points and, at the same time, minimizes or eliminates the WEAK points. Let’s take a quick look at each system 

  1. Liquid Chlorine (sodium hypochlorite) 

Strong points: Liquid chlorine is manufactured by large companies and is shipped from outlying areas to warehouses, and then, in most cases, is purchased by pool service companies and delivered to the pool, or is sold to retail stores and purchased by pool owners.

It is fast acting, releases free available chlorine, is relatively inexpensive in comparison to other sanitizing products, and is relatively easy to use. 

Weak points: It is concentrated it is  hazardous to transport, handle, & use. Accidents are reported every year from people misusing this product. Over 90% of what is in a bottle is inert ingredients (junk) the manufacturers must add because chlorine is so unstable. This junk ends up part of your pool water and raises the total dissolved solids with each gallon added. This is not an environmentally friendly product. Most of their hazardous containers end up in our landfills.

Chlorine Genie’s Solution   

Pure chlorine is manufactured inside the Genie and is dispensed to the pool seconds later. Our only inert ingredient is a small amount of household water. It is extremely safe; no containers are used which makes it very environmentally friendly.

  1.  Pills and Tablets (…………..)

Strong points:  Tablets usually come in five-gallon buckets and store well if kept in a safe, dry place. When this product is used in dispensers or floaters the chlorine is slowly released. This tends to keep the chlorine at a more stable reading. 

Weak points: Reading the warning labels on these buckets  is scary. Chlorine in its pure form is a gas. The white powder that many manufacturers use to make the tablets is cyanuric acid.  As the tablets dissolve and release their chlorine they also release cyanuric acid (or stabilizer). Stabilizer is like aspirin, a little can be helpful, too much can be a big problem. The Board of Health recognizes the benefits of stabilizers in the water but if the stabilizer is over 75ppm they will lock the gate to the commercial pool and require it be drained. Because of this, in some states stabilizers have been banned.  

Chlorine Genie’s Solution   

No cyanuric Acid is manufactured in our system. We do recognize the benefits of a controlled amount of stabilizer. We recommend 40 to 60 ppm. This is accomplished by adding a little each season.

  1. H.T.H granular chlorine (calcium hypochlorite)

Strong points:  This is probably the most inexpensive form of chlorine available. It stores well and the percent of chlorine is fairly high. There are feeding systems that can be purchased to automatically feed the powders and pills to the pool.

Weak points: This is also a dangerous and hazardous product to store (read the labels). One of the most common stains on  pool plaster and tile is calcium. The by-product of HTH is calcium. When you have excessive calcium in your pool water and you let the pH go above 7.8 you will cause calcium to deposit, not only on the tile and pool plaster, but also in your heater & filter. 

Chlorine Genie’s Solution   

Calcium is an enemy to any chlorine generator! It is not a good substance to have in any pool. That is one of the main  reasons no pool water is used or enters the Chlorine Genie. Only softened household water. 

  1. “Salt in the pool” type chlorine generators 

Strong points:  In the last few years these units have become popular. They produce chlorine from the salt that is added to the pool. As this salted pool water goes through an inline cell in the pools plumbing, chlorine is generated. As long as the pH of the water is kept right, the water in the pool is comfortable for the swimmer. The monthly cost for chlorine is low and chlorine is dispensed to the pool every day while the filter system is running.

Weak points: The basic idea of dumping hundreds of pounds of salt into the pool is a bad idea. Salt is corrosive and can cause problems on the pool surface, plumbing, and surrounding landscaping. Dumping salt into the pool raises its total dissolved solids. This condition can cause depositing on pool walls and equipment. Salt water pools are being outlawed in some areas because when draining the pool salted water cannot be recycled. (see ******) The pool water that exits an inline cell is high on  the pH chart. The pool owner must test and watch pH closely. Some manufacturers even recommend an acid feeder with their unit to solve this problem. Running hard pool water through an inline cell causes calcium to deposit on the negative electrode shortening its life and efficiency. These cells must be removed and cleaned with acid periodically.

Chlorine Genie’s Solution   

Chlorine Genie puts its salt in the unit not the pool. We bring a small amount of household water to the Genie then we run the water through a built-in water softener. Our cell is submerged in softened brine water not hard pool water. Our cell manufactures its own acid and base product. This allows the Genie to adjust the pool pH up or down without using commercial chemicals. With our cell submerged in softened brine water, it makes more chemicals with much less power. Bottom line is we have developed the most efficient pool water management system on the market today.

  1. Weekly pool service 

Strong points:  I will not say  much here. Many pool service people are selling the Genie’s. Having a person checking the pool’s chemistry weekly is a good idea. They can also check the filter system and keep it running properly. 

Weak points: This is the most expensive method for pool water maintenance. Most services use a combination of liquid chlorine and tablets. (We  have already discussed the drawbacks of these products.) Basically, putting chemicals in a pool once a week is a bad idea. The Board of Health will not  allow that on a public pool. One day the chemicals are too high and 7 days later they are too low. Most services are in such a hurry they can’t afford to spend much time in your backyard so you end up spending $100.00 per month for four calls or about $100.00 per hr. Expensive but convenient.

Chlorine Genie’s Solution   

What can I say:

  • The Genie gives you daily chemicals.
  • Allows you to swim in fresh unsalted crystal-clear water.
  • Makes its own acid and base product for pH adjustment. 
  • Uses only softened tap water not hard pool water. 
  • Has over 40 patent claims issued by the patent office. 
  • Has been tested and certified by NSF (National Sanitation Foundation).
  • Is being used by thousands of residential and commercial swimmers.
  • Is setting a whole new standard for a safer and easier system for pool water maintenance.
  • Is extremely easy to install. 
  • Can be purchased factory direct by pool owner.
