Chlorine Tablets for Swimming Pools Buying Guide

Chlorine tablets are the most widely used pool disinfectants in the world. The fact that they come in the solid-state greatly reduces the danger of spills and makes them very convenient to use.

Our buying guide reviews the best chlorine tablets for swimming pools based on their specifications and customer feedback to give you the best options to choose from. We then take it a step further to outline the important considerations you should make when considering a product before you make a purchase.

Chlorine Concentration

The chief active ingredient in chlorine tablets is the chlorine compound. And so, the chlorine concentration in the tablets you are considering should be your first consideration to make. The higher the concentration of chlorine, the more effective and longer the disinfection of your pool will last.

Pool Size

The size of your pool is also another important consideration to make. The larger your pool, the larger the pack of chlorine tablets you want to buy so they last you throughout the summer. Most chlorine tablets come in 1’’ or 3’’ sizes, with all the products listed above of the latter. These ensure week-long disinfection. For smaller pools, you can go with smaller packs. Note that the larger packs are however, more cost-effective.

Stabilized vs. non-stabilized

Chlorine tablets are generally classed into stabilized and non-stabilized products. Stabilized chlorine tablets are the most common and contain a stabilizing agent to resist the breaking of hypochlorite solution when exposed to sunlight. It turns out that the UV rays in sunlight are the natural nemesis of chlorine and can greatly reduce the concentration by as high as 90% in a few hours. The stabilizing agent prevents this and thus makes them ideal for outdoor pools.

non-stabilized chlorine tablets do not contain a stabilizing agent and are rendered ineffective if exposed to sunlight. This makes them ideal for indoor pools where the sun doesn’t reach.

Price

Like any product on the market, chlorine tablets for swimming pools come in widely varying prices depending on quality and size. It is always a great idea to check for customer reviews and feedback on particular products you are considering to be assured of their quality.
