Start the Season Right - Save 10% on All Chemicals and Filters

As we move into spring, it is the perfect time to get your hot tub, spa or pool ready for the months ahead. After the winter period, many spas benefit from a bit of attention - especially when it comes to water treatment and filtration.

To help you prepare, Hydrospares is offering 10% off all chemicals and filters from 23rd to 31st March.

The Perfect Time for a Fresh Start

If your spa has been used less over the winter, your water chemistry may not be as balanced as it should be. Filters can also become clogged with oils, debris and general build-up over time.

Starting the season with fresh filters and the right chemicals helps keep your water clean, clear, and ready to use, this helps your equipment run more efficiently, in turn reducing strain on pumps and heaters.

Replace Your Filters

Filters play a crucial role in keeping your water in top condition. They capture dirt, oils, and small particles from the water as it circulates through the system.

Over time, filters naturally wear out and become less effective. Replacing them at the start of the season is one of the easiest ways to improve water quality and keep your spa running smoothly.

With 10% off all filters during the promotion, it is a great opportunity to stock up on replacements. Trade customers can maxmimise savings by taking advantage of our bulk-buy options.
