Frequently Asked Questions (FAQ)

What is the best floating chlorine dispenser?

Floating chlorine dispensers are a simple and effective method of maintaining your swimming pool water. They disappear into the pool and release free chlorine. They float at the surface and gently dissolve to slowly introduce chlorine into the pool water.

The main draw of the floating chlorine dispensers is the obvious ease of use and switching between different types of chemicals is a breeze. If you find a different chemical works better than chlorine in the long run, simply use a different floating chlorine dispenser for your pool water. The water stays clear and sanitary no matter what type of additive you choose to put in. Boasts typically range from 1,500 to 3,000 gallons per dispenser.

What is the best chlorine dispenser?

A floating chlorine dispenser keeps track of the amount of chlorine in the pool. An automatic system does the job for you, while manual chlorine dispensers require your attention. With an automatic dispenser, there is no measuring or adding chlorine to the pool. These are systems worth investing in, especially if they are one of the best chlorine pool dispensers. Chlorine dispensers can be installed on the pool when you install the pool so you don’t have to worry about it during the summer months.

In the event you own a pool that isn’t very deep, an automatic chlorine dispenser may be too large. A manual dispenser that you can hang from the pool wall will likely be much more suitable. Most manual chlorine dispensers have a hook that can be easily attached to the side of the pool.

How many floating chlorine dispensers do I need?

The number of floating chlorine dispensers you will need depends on the size of your pool. The larger the pool or spa, the more floaters you will need. For larger pools incorporating spas or pool with separate hot tub sections, the calculation is a bit more complex.

The basic rule for determining the number of floaters required is:

Should I use a floating chlorine dispenser?

A floating chlorine dispenser is a great way to keep chlorine levels up in your pool. However, it isn’t necessarily the most practical solution.

For one thing, using a dispenser means you don’t have to manually add chemically treated water. You also don’t have to stick your hand in a chemical bath every time you want to check the chlorine level.

Instead, the dispenser will release a measured amount of chlorinated water into your pool. This is not only a safer method than using a bucket, but it is also less wasteful. The less water you waste, the less maintenance you need to perform.
