What does hth Bright Water 3 in 1 liquid do?

hth Bright Water 3 in 1 liquid is designed to work in conjunction with hth Spa Active Oxygen Tablets.  Between them they will give you hot tub water which is beautifully clear and a pleasure to soak in.

The system comprises of the liquid activator and a 20g active oxygen tablet. Used correctly, it offers a gentle alternative to using either chlorine or bromine. The system is easy to use, has no discernible odour and is kind to your eyes and skin.

There are some important steps to take before converting an existing spa to hth Spa Active Oxygen.  The same applies when setting up a new spa.  Firstly, always check the procedure outlined in the leaflet provided. It is also important to maintain pH levels within the range of 7.2-7.6 at all times.

How does it work?

Initial dose:

As part of the initial treatment process, simply add four hth Spa Active Oxygen Tablets. You can do this via a floating dispenser or directly into the filter area of your hot tub. You will also need to add 30ml hth Bright Water 3 in 1 liquid per 1,000 litres of spa water.

Ongoing treatment:

  1. Before bathing just add one tablet per 1,000 litres of spa water into the filter area of your hot tub.
  2. Once a week add 30ml hth Bright Water 3 in 1 liquid per 1,000 litres of spa water, and 2 tablets.
  3. Test the Active Oxygen levels with Aquachek Active Oxygen Test Strips for Monopersulfate, Alkalinity & pH test strips. Ensure the MPS reading indicates OK to high (5-10mg/l).
  4. Midway through the week add another 2 tablets to the filter area of the spa.
  5. For best results, a weekly application of Aquasparkle Spa Fusion Oxidiser aqua sachet is essential to eliminate non-filterable spa contaminants.
