Things to consider before buying a best pool chlorine granules

Chlorine level in your pool

Chlorine level should be between 1.0 ppm and 3.0 ppm (parts per million). If you are using a chlorine test kit, it will tell you exactly what the level is. If you don’t have a test kit, then there are simple guidelines that can help you determine if your pool needs more or less chlorine:

  • It’s easier to see when the water is clear or cloudy. As mentioned above, cloudy water makes it hard to see whether or not there is adequate chlorine in the pool; however, if your water is clear enough that you can clearly see through it without any trouble—and especially if there’s no algae present—then adding more will probably do nothing except waste money!
  • On the other hand, if there’s algae in your pool (green stuff growing on top), then increasing levels of chlorine may help destroy it in short order (though there are other methods for dealing with algae).
  • Check how strong smells are coming from your equipment when turned on vs shut down after some time has passed since last use (i.e., overnight). If something smells strongly while turned off but not while running properly after running for awhile (e.g., 10 minutes), this could be an indication that too much has been added recently and now needs removing through flushing out some lines/systems before re-starting up again tomorrow morning early morning so we’re ready for guests coming into town later tonight.”

Dissolving speed of the granules

When it comes to chlorine granules, the slow dissolve option is generally best for pools, hot tubs, spas and jacuzzis. Fast dissolving granules are better suited for use with ocean water or other heavily chlorinated bodies of water.

Calcium hardness level

If you have a calcium hardness level of over 400 ppm, use a product that contains calcium sequestrant to lower it. If your calcium hardness is below 200 ppm, then use a product that contains salt and chlorides (a chlorine generating system) to raise it.

The pH levels are perfect.

The pH level is a measurement of acidity or alkalinity in water. The scale ranges from 0-14 with 7 being neutral, below 7 being acidic and above 7 being alkaline. Ideally, the pH should be between 7.2 and 7.8 for swimming pools to prevent eye irritation and other skin irritations caused by the high chlorine content in such pools.

To test your pool’s pH level, you need to buy an inexpensive test kit that you can find at any hardware store or supermarket once you have identified which brand of granules you want to buy as well as how much it costs per pound (or kilogram) of granules based on its cubic foot size (when it comes in other packaging).

You may also need a bucket full of water from your pool if the instructions call for mixing 1 gallon (3 liters) with 5 pounds (2 kilograms) of granules; depending on how many gallons there are in your pool!

The best pool chlorine granules need to be used as per instructions and should be compatible with the pool water.

  • Pool chlorine granules should be used as per instructions, and they should be compatible with the pool water.
  • You need to ensure that you are using the right kind of pool chlorine granules for your swimming pool.
  • The best thing to do is read the label on the bottle of pool chlorine granules and make sure that it is compatible with your type of swimming pool by checking if it has any warnings or cautions written on it.


The best pool chlorine granules have a long shelf life, which is an important consideration. They do not contain any harsh chemicals and are eco-friendly, so there’s no need to worry about your children and pets playing around in the water. The best pool chlorine granules are safe for all types of pools, even those that are slightly acidic.

The most important thing to remember when buying a product like this is that you should always read the instructions carefully before using it. As well as this, make sure to use these products in accordance with your local laws!

Chlorine granules are a great choice for disinfecting your pool. They’re easy to use, safe to handle and can last for months. It’s important that you choose the best product so you get the most value from your purchase. As we have discussed above chlorine is an oxidant which means it will damage anything organic (e.g., algae or skin cells) when used properly.

However if handled improperly it can be dangerous due to its volatility as well as its ability to cause irritation/burns on contact with eyes or mucous membranes such as those found around ​​​​the nose and mouth area
