Sanitizing your hot tub water should be a serious affair that you should not take it lightly for the benefit of your health and relaxation.
There are various sanitizers which are commendable for using in your hot tub water. Among these sanitizers you find bromine, chlorine, mineral-based, and biguanide-based.
Sanitizers are therefore classified according to what they contain for sanitization:
Have you ever heard of water being shock treated? This is chlorine’s method of sanitizing water. It is a formula that induces shock to the hot tub water. With its kind of treatment, it burns off organic matter and clears water off its cloudiness leaving your water clear and clean.
Since its granules dissipate quickly it needs the support of another sanitizer for a continuous sanitization process. It also can irritate skin especially to those with sensitive skin. It can smart the eyes when they come into contact with chlorine treated water. Extensive use of chlorine can wear your hot tub cover due to its bleaching effect.
Bromide provides continuous sanitization to your hot tub water. For it to work effectively, it has to have a bromide feeder where bromide tablet is inserted to release slowly in the water.
It irritates skin and leaves behind its chemical odor. Otherwise, it works excellently. Extensive use of Bromide can wear off your hot tub cover due to its bleaching effect.
Mineral sanitizer is environmentally friendly because of its mineral use. It can either use silver or copper ions or even both to clean your water and sanitize your it.
The use of copper for water sanitization reflects old methods in the ancient days. Water containers were made of copper to retain water freshness for a more extended period.
Nevertheless, there is no method of measuring silver or copper content in the water, and thus the user must observe the instructions and dosage to maintain effectiveness.
Biguanide lacks oxidizing formula and therefore cannot break down contaminants such as body oils, sweat, and other body chemicals. Thus, when using biguanide, you should accompany it with an oxidizer to help breakdown the contaminants.
Nevertheless, biguanide does not weaken under high temperature, unlike chlorine. Again, since it does not contain any oxidizing formula, it does not leave behind the lingering smell. Since it does not provide any bleaching solution, it does not wear out vinyl liners in your hot tub or bleach your swimming costume.
The downside of biguanide is that some microorganisms can become resistant to biguanide and therefore become less effective. Also, slime caused by algae can occur even under biguanide sanitization.
While looking for a sanitizer for your hot tub water, check the content of water required for its use. Some sanitizers would require specific amounts of water which might be lower than what you have in your hot tub or vice versa.
From what we have discussed concerning chemicals, check the base chemical of your sanitizer. If you are changing a specific sanitizer probably due to some skin reaction, see that what you choose next does not have the same chemical base.
Also, consider the ones that can last longer with one application. Some can take as long as four months while others go for seven days.
The use of a sanitizer is to protect you from contaminants and other microorganisms that might cause health problems. In that case, you should consider going for a sanitizer that is environmentally friendly and for your health safety.
Check the label for any information on allergies or side effects to know which might work for you and your guests without causing harm.
The safety of your hot tub is also essential. Check what sanitizer suits your type of hot tub. Some sanitizers can ruin your hot tub cover on the underside while others can destroy your equipment. Choose the one that is compatible with your hot tub.
It is vital to know what others are saying about your choice of hot tub sanitizer before acquiring it. You might need to check the reviews on that particular product.
The price of the sanitizer will be a big factor to consider and mainly if you are concerned with the budget.
Q: Why is it essential to sanitize my hot tub water?
Sanitizing your hot tub water will purify it by killing bacteria and other microorganisms. Hot tub water is a hive of contaminants such as body fluids, body oils, body wastes, lotions, and many others. Since the water in a hot tub has a high temperature, the bacteria can thrive quickly.
It is therefore to sanitize your hot tub water all the time to enjoy clean and germs-free water.
Q: Why is chlorine not the best sanitizer for my hot tub water?
Using chlorine in hot tub water can be excellent only if the water was not hot. Since water in a hot tub is hot and steamy it can leave unpleasant smell from the use of chlorine. This is the reason why chlorine is not popular for sanitizing hot tub water.
Q: What are the advantages of using mineral based sanitizer?
- It is cost-effective
- Less usage of chlorine
- Easy to use
Q: How do I check silver ion content while using mineral sanitizers?
There are no test strips to check silver content in this system but only copper test strips which are available. Therefore, when using this water-sanitizing system, Be careful on instructions dosage so that you may not exceed or apply less than needed.
