Chlorine Tablets Vs. Liquid Chlorine

Another pool season is here.   If you spent too much last summer fighting algae in your pool, then you might want to consider other options this season.  One of those options is a salt water system.   Depending on the size of your swimming pool, this system will cost between $1,000-$2,000.   This includes the cost of the salt.   If you have a large commercial swimming pool, then it will cost more.

If you don’t have the budget to convert your pool to salt this summer, then you might want to consider switching to liquid chlorine instead of chlorine tablets.

In this post, I will discuss both options so that you can decide what works best for you.


This is the option that most pool owners use.   Chlorine tablets are the easiest way to chlorinate your pool.   It is also the cheapest way as well in the short term.  In the long term as in years-there are cheaper options for chlorinating your pool.

The chlorine can be put in the pool skimmer or in floaters put in the swimming pool.  If you want to be able to put in as many as possible, then we suggest having a chlorinator installed onto your pool plumbing.   That can usually be done on most existing pool plumbing.  It rests on top of pool plumbing.   Or, it can sit on the concrete next to the plumbing.  It all depends on the pool equipment pad and whether there is space.

All chlorine is not equal.   Those purchased in the sporting goods department of a big box store are not the same as those purchased from the pool store or supplied by a pool service provider.   The ones provided by a pool service provider are going to have a higher concentration of chlorine.   This is the best type of chlorine to use.

If you purchase the cheaper ones, then you will need more to chlorinate your pool because of the rise in cyanuric acid levels in your pool.   The higher the CYA levels, the more chlorine you will need.  And, in a chlorine tablet pool, you cannot control the CYA levels.


The other option is liquid chlorine.   This is where you have special bins of varying sizes placed on your equipment pad.  If your Pool Technician is skilled, then he can connect the chemical lines to the pool plumbing from the containers where the chemicals are stored.

The pool technician will then set up automatic feeders that draw the chlorine out of the bins and circulate it through your pool plumbing and pool filter.

One of the positives about liquid chlorine is that it can feel softer to the touch when swimming in a pool with liquid chlorine.   The water will almost feel as if the pool had a salt water system that made chlorine.

Liquid chlorine can be a good option if you are trying to limit having to put chlorine tabs in your pool to make sure that it is chlorinated.   Once the equipment is set up properly, then you only to have to check your feeder, maybe once a week to make sure that the chlorine is feeding properly to the pool.

If you choose to not convert to salt, these are the two options for chlorinating your pool.   Make sure that you choose one that you will be happy with and will work with your current budget.
