There are now many water care products available for hot tubs that claim to dramatically reduce chlorine use with some, falsely and dangerously, even claiming to allow no use of chlorine in portable spa water. While most of these products are useful additions to spa water care, improving the “feel “of the water as well as reducing the chlorine requirement, none of them does away with chlorine or bromine, while some owners have been incorrectly advised to use Tri-Clor tablets to ensure hot tub water remains safe but in doing this hot tub equipment and finishes have been damaged.
What is common for all these alternative products is very good marketing and packaging and very high prices, typically £85 for 3 month supply. Many spa dealers also play the eco line with products or claim their treatments are only required once a week or do away with chlorine completely by the use of enzymes or bio film removers, all claims that are both incorrect and misleading. The main reason hot tub dealer push these products is they promise a much higher margin than chlorine, that is heavily discounter on the market, and prices are usually fixed at a high level by distributors, always obvious when all prices for a product are much the same.
Mineral low clor technology for hot tub water treatment.
For many years mineral technology has been used successfully on hot tubs improving water feel and dramatically reducing chlorine use, the active ingredients, that are all forms of silver, copper and zinc, are usually dispensed by in line cartridges or canisters placed in the filter area and work well; typically being active over a season and reasonably priced. All these low chlorine systems work in conjunction with a regular and approved sanitiser, like di clor granules, that do not much effect pH and are not damaging to the hot tub and its equipment.
