How to keep your hot tub water clean?

No matter how fast technology evolves, there can never be a full self-cleaning spa or hot tub. The small features used in cleaning a spa or hot tub are cared for by the inbuilt system, but when it’s about general care and maintenance you personally will have to get to serious work often.

Below are guides that offer various possible ways of keeping your water clean so you or your guest won’t get infected with diseases caused by dirty water.

Keeping water clean is more than just making the hot tub neat, here you will get to read some examples that might keep the water clean for a long while until the next cleaning date. And note that because the water looks clean doesn’t really makes it clean.

Cleaning and sanitizing

Bacteria are known to grow spontaneously especially in warm water when left unkempt, this makes water sanitizing a great means of killing all germs and cleaning the pool. The most common substance used is the same one used for swimming pools, and it is called “chlorine”. There are majorly two types and the required one for you is the Dichlor. But the Trichlor must be avoided when sanitizing the spa or hot tub, but are commonly used for swimming pools.

The Trichlor simply becomes very corrosive in all warm water to an extent that it could void the warranty and make serious damages to the hot tub and this is the main reason why it has to be avoided. The precise quantity of chlorine is quite beneficial when used in a hot tub and if properly administered it won’t result in side effects like itches, smell or even rashes. It is available in different forms which are granules and tablets, chlorine needs to be the first line of defense when it comes to caring for the water.

Bromine is another secondary solution and it’s available in different forms like nuggets, granules or tablets. It strongly requires an oxidizer for an optimal effect which is the main reason it’s been sold as non-active and active. The active type includes chlorine and saves you the problem of non-active usage which requires an oxidizer to perform effectively. Some consumer likes Bromine better as their sanitizer since it does not really give much odor unlike chlorine and really does not gas off when temperature rise is above 980. Your preference over the other is totally your decision because both the chlorine and bromine are the same price. The last on list gaining much popularity as a sanitizer for the hot tub is the Biguanide, and it’s the only non-bromine and non-chlorine method of sanitization on our list. This third option is a viable one especially for keeping your water clear and clean if you have allergies to the two chemicals priorly mentioned or probably you just dislike them. Biguanide is more effective and efficient at eliminating bacteria and it gives lesser odor than other sanitizers. What makes it more attractive is that it does not gas off at very high temperature but its drawback is that it’s not compatible with enzymes system.

Cleaning the hot tub

The most simplified way to maintain clean water is by constant changing of the water with a recommended cleaning interval. Cleaning is not just about discharging water and spraying the hot tub sides but making sure the filter that makes water clean is properly cleaned out. Making sure the filter is clean insinuate that it will always be in perfect shape in cleaning the water while in or out of it. Hot tub retailers sell different solution specifically for cleaning the hot-tub’s filter so it could last longer before replacing it. A filter regularly cleaned has a longer life span that could last about to a year than most normal filters. So at this point, it’s not just a cleaning agent but cost effective.

Just like the regular bath-tub a spa and hot tub can be infected with a scum ring. Replacing the water on a regular basis and the use of a good sanitizer will serve as a good prevention method, but if you would like to be precise you can get a scum ring specific product. This product will be specific at mitigating the source of scum ring build up and helps with sanitation processes. As the last line of defense on keeping the hot tub clean, you can avoid dirt from getting into it by covering it with its cover. A lot of debris and dirt that find their way into the hot tub is not always from people but also from other outside elements when it’s not used.

Leaving the top of your blow up hot tub uncovered when it is not being used only attracts different things to land on it and this allows the needed heat to escape from it. This causes the pump to work overtime in order to keep up with the preset temperature as a result of this you tend to spend more. Make sure the cover of the hot tub is kept clean so you won’t have much work to do when covering it. A big regular mistake which is always made with the hot tub cover is that when it’s tossed to the ground and then tossed back on the hot tub. Apart from the fact that you will be inviting dirt from the grass to invade the water, be sure to see unwanted pest being invited. When you properly care for the hot tub cover be assured that your hot tub will be cared for.


Now you can realize that there are various ways which your spa and hot tub water can be kept clean, with many costing you your precious time than your money.  It’s not that costly to maintain a hot tub and the water if a hygiene and sound preventive measures are practiced. With time it will all become an automated device. Always remember to rotate the water often and that it being clear means it is not dirty. The careful use of the above guides and method will make you and your family enjoy a year round clean and clear water.
