Chlorine Pool Tablets Vs Liquid Chlorine?

Why pool chlorine tablets? Well, here's why.

Stress-Free Application

These tablet swimming pool additives are easier to apply than their liquid counterparts. All you need is a tablet floater dispenser, and you never have to worry about carrying gallons of liquid chlorine around.

Efficient and Economical

Tablet packaged pool chlorine will also save you much money in the long run. When these stabilizers get released and exposed to the sun's ultraviolet ray's chlorine wastage is eliminated, ensuring that every bit of chlorine is efficiently utilized and no part of the water has more chlorine concentration than the other.

Chlorine tablets, without a doubt, last longer than liquid chlorine as only the needed amount of chlorine is released per day, hence saving you much money.

Longer Storage Time

These tabs have a longer shelf life in comparison to liquid chlorine. Liquid chlorine can only boast of shelf life of 6months while tablets have a shelf life of 3-5years,

Stress-Free Measurement

Another reason why tablets are the go-to for most pool owners and maintenance personnel is that tablets are already premeasured; the manufacturer has done the bulk of the work; all you need to do is to apply the right amount of tablet to your pool depending on your pool size.

What are the Types of Pool Chlorine Tablets?

Before choosing pool chlorine tablets, you need to be aware that there are two categories of pool chlorine tablets. The location of your pool and the pH of the water and will determine the appropriate type of chlorine tablet you should use.

Unstabilized Chlorine Tablets

This category of pool chlorine tablets includes sodium hypochlorite, which is perfect for waters that struggle with high hardness levels; it has a 10-12% chlorine concentration. There is also lithium hypochlorite with 28-35% chlorine and calcium hypochlorite with 65% chlorine.

Although unstabilized chlorine tablets are quite effective and offer a quick treatment when the pool needs to be used regularly, their greatest enemy is sunlight, making them quite vulnerable to UV radiation.

Stabilized Chlorine Tablets

Stabilized pool chlorine tablets are suitable for outdoor pools because they are composed of cyanuric acid that acts as stabilizers and prevents them from dissolving fast. Examples of these stabilized pool chlorine tablets include Dichlor with 56-62% chlorine and Trichlor with a chlorine percentage of 90%.

What are the Things to Consider When Choosing the Best Pool Chlorine Tablets?

To choose the best chlorine tablets for your pool, here are some important things to consider.

Tablet Size and Pool Capacity

To choose the best chlorine tablet for your pool, you need to know the pool capacity and choose the appropriate size tablet for the pool. These two works together to ensure that you get the results you desire. Chlorine tablets for pools are majorly available in two sizes; 1-inch tablets and 3-inch tablets. The 1-inch tablets are suitable for small pools with a water capacity of fewer than 5000 gallons. This means you can use them in your hot tubs and spas. The 3-inch tablets, on the other hand, are more suited for bigger pools; however, they dissolve much slower.

Tablet Dissolution Speed

Another important consideration that must not be ignored when choosing chlorine tablets for your pool is the dissolving speed of the tablet. 3-inch sized tablet, as stated earlier, dissolves at a much slower pace than the 1-inch tablet; however, the speed of dissolution is not limited to the size alone; it can also be a factor of the method of application you choose.The speed of dissolution of the chlorine tablet has to be just perfect. If the dissolution speed is too fast, it will shock the water and make it unsafe to swim until the chlorine dissipates completely. At the same time, too slow a speed will lead to a chemical imbalance and disproportional distribution of chlorine in the water.

Tablet Composition

As seen earlier when we discussed the different types of pool chlorine tablets, chlorine tablets have different chlorine concentrations, so it's important you check and confirm if the percentage of chlorine in the tablet and ensure it is well above 60%. The chlorine tablet should contain a stabilizer that won't dissolve excessively fast when exposed to sunlight.

Tablet Packaging

Pool chlorine tablets are packaged in different ways by different manufacturers; it is important that you choose tablets that come in smaller package sizes; they are less prone to shipping accidents. When handling these chlorine tablets, whether each tablet needs to be unwrapped or not, we advise you to wear durable protective gloves, goggles, and a mask.
