Things to be considered before buying hot tub chemical: Buying Guide
It is important to know exactly which type of chemical is suitable for your hot tub to narrow down your options and select the best one. Hence, we have laid the main criteria which one must consider to understand if the required chemical is compatible with your requirements or not.
Here are some of the factors which you must consider before buying an appropriate hot tub chemical for sanitizing purposes:
Size of the tablet
When you choose a chlorine tablet, it is mainly available in two sizes – 1” and 3”. Depending on your pool size, the size of the tablet you choose varies. For the bigger pools, you need bigger tablets to work faster and more efficiently.
Composition of chemicals
Generally, sanitizing chemicals are made up of different variants. The appropriate levels of chlorine and bromine must be available in the composition to make it work effectively. For sensitive skin, the chemical with a higher composition of bromine is highly recommended.
It is another important consideration that adds to the durability of the tablet. Many manufacturers wrap individual tablets to avoid any damage during shipping. The liquid chemicals available in the bottle should be handy and easy to open.
As the chlorine tablets are fragile, if mishandled they will get broken easily. The broken tablets dissolve quickly and will not last longer as expected. Hence, look for smaller packaging which has lesser chances of mistreatment as compared to the bulky ones.
The tablets with higher dissolving speed are prone to ‘shock’ you pool with high chlorine content, making it unsafe due to higher chlorine dissipation. However, if the dissolving speed is quite slow, it will not work up to the mark and will not clear the water as expected.
Hence, depending on your pool usage, you should choose the chemical/tablets with a moderate speed which varies from 7 to 10 days.
Choosing an ideal hot tub chemical depends on many factors like choice of primary chemical – bromine or chlorine, size of your pool, frequency of usage and the price. Hence, it is very important to outline your requirements first and look for the chemical which can largely suffice your needs.
There are many manufacturers which offer great deals on bulk purchases. However, the tablets being fragile are prone to higher breakage in the bulk packaging. It is important to choose the right chemical to keep your spa free from algae, bacteria, and odor.
So, make your pool safe and ready to swim by using the right chemical without pinching your pockets.
