Water Care And Hot Tub Maintenance

Clean Spa WaterIn order to get the most from your hot tub experience, clean and hygienic water is essential. Heated water can be a breeding ground for harmful bacteria. Fortunately a portable hot tub is not difficult to keep clean and free from these nasty’s. A little hot tub maintenance is all that is required.

You do not need to have a degree in chemistry to be able to maintain a well-balanced and sanitized spa. Just follow these simple guidelines and your hot tub will always contain luxuriously soft, clean and safe water.

Using Chemicals

Chlorine is a very effective hot tub and spa sanitizer. It usually comes in a granular or tablet form and is quick and easy to use. Ideally you should use between 3 and 5 milligrams of chlorine for every litre of water.

The use of a sodium dichlor based chlorine is recommended for portable hot tubs. Sodium dichlor is neither too alkaline or acidic and does not loose its effectiveness with high temperatures. It is specifically designed for hot tub use. It is best dissolved first in a small container of water and then added to the hot tub.

Because chlorine can sometimes release an unpleasant odour when water temperatures get above 98 degrees, many people prefer to use bromine. However if you do not intend to run your portable hot tub at such high temperatures then chlorine will work fine.

Floating Bromine DispenserAn alternative to chlorine that is very popular is bromine. The two most common varieties of bromine are sodium bromide and BCDMH which stands for bromo-chloro-dimethylhydantoin. An activator like chlorine or potassium is required when using sodium bromine. Because of this BCDHM is the easiest to use. It is self-activating and requires no other additives. Bromine works effectively in hotter water than chlorine, however because it is light sensitive it may require more tops ups than when using chlorine.

Bromine has a lot of advantages over using chlorine in your portable hot tub. It is more expensive than chlorine, but if you make sure to cover your spa when not in use it will last longer and do a better job of keeping your spa water bacteria free.


Clean SpaHot Tub Filter CartridgeMost water contains mineral and chemical particles. Over time these will clog your filtration system. Cleaning your filter cartridges once a month will ensure good water flow in your hot tub. Spraying with good pressure from a garden hose to remove calcification and debris from the filter pleats is all that is required. If the sediment build up on your filter cartridge is severe a filter cleaner may be used to bring them back to life. Depending on your water quality filters should be replaced every 6 to 36 months. You can only clean them so much before the integrity of the filter itself will fail.


Scrubbing Hot TubYour hot tub water will only ever be as clean as the surfaces that surround it. A good scrubbing every 2 months to get rid of calcification, scum and other residue on the exposed walls of your spa will keep things sparkling and clean. Skin flakes, garden debris and mineral deposits will build up on the walls and crevices of your tub, if you do not apply some generous elbow grease from time to time.

Common household baking soda works well to clean the smaller surface areas, while scale removers can also help when the build-up is severe. Spa shining agents are also available; using these will restore the lustre and make your tub feel like new.

The same cleaning regime should apply to your hot tub cover as well. Although this may not be in direct contact with the water, nothing looks less inviting than a hot tub with a stained and dirty cover on it. To limit UV degradation from the sun you can use special conditioners designed to protect and ensure the cover does not harden and crack.

Always keep your hot tub covered when not in use, and if possible shower first to help reduce skin residue, oil and grime. Avoid wearing coloured cotton in your spa, as these tend to bleed when soaked in warm water treated with chlorine. Try to develop a routine that includes regular hot tub maintenance. You will be rewarded with a consistently clean and hygienic hot tub.
