Full details

This guide is for hot tub and swimming pool owners seeking a reliable way to maintain safe, bacteria-free water. The key benefit is the slow-release, stabilized chlorine that minimizes sunlight loss and effectively kills harmful organisms. A potential caveat is the need to closely monitor and adjust pH levels for optimal performance. These 20g tablets offer a long-lasting solution for regular dosing, designed to have minimal impact on water pH.

FAQs

How often should I add chlorine tablets?

This depends on usage and water conditions. For hot tubs, check levels daily and add tablets as needed to maintain 3-5 mg/l. For pools, check levels frequently and replenish to maintain 1-3 mg/l. Slow-release tablets typically last 2-4 days.

What is the difference between hot tub and swimming pool chlorine levels?

Hot tubs operate at higher temperatures and with more concentrated use, requiring a higher free chlorine residual of 3-5 mg/l. Swimming pools have lower usage density and ambient temperatures, requiring a lower residual of 1-3 mg/l.

Can I use these tablets in a saltwater pool?

These are multifunctional chlorine tablets and are generally not recommended for use in conjunction with saltwater chlorine generators, as they add a different form of stabilized chlorine that can interfere with the salt system's function.

What should I do if my pH is not in the recommended range?

Before adding chlorine tablets, adjust your water's pH to the ideal range of 7.2-7.6 using appropriate pH adjusters (pH Plus or pH Minus products).

How long do the tablets last?

The tablets slowly release chlorine over approximately 2-4 days, depending on the water flow over them and the water temperature.

Can I put the tablets directly into my hot tub or pool?

It is best to use a floating dispenser, chemical feeder, or skimmer basket to ensure a controlled and consistent release of chlorine. Direct addition is not recommended for sustained sanitation.

Are these tablets safe to use with colored pool liners?

These tablets are designed to have minimal effect on water pH. However, to prevent potential bleaching or discoloration, it's advisable to use a dispenser and avoid direct, prolonged contact with surfaces.

Troubleshooting

Water not staying clear or has a persistent odor.

Check and adjust pH to the 7.2-7.6 range. Ensure free chlorine levels are within the recommended range (3-5 mg/l for hot tubs, 1-3 mg/l for pools) by adding more tablets or adjusting the dispenser. Consider a shock treatment if water quality is poor.

Chlorine levels are too high.

Reduce the number of tablets in your dispenser or decrease the flow rate of your chemical feeder. Allow the chlorine to dissipate naturally, especially if the water is not in use.

Tablets dissolve too quickly or too slowly.

Adjust the aperture on your floating dispenser or change the flow rate on your chemical feeder. Water flow and temperature can affect dissolution rates; higher flow and temperature lead to faster dissolution.

Product causes skin or eye irritation.

Ensure proper water balance, particularly pH and chlorine levels. Always remove dispensers from the water when bathing in a hot tub and rinse off thoroughly after swimming.

Pros and Cons

Pros

  • Provides consistent and long-lasting water sanitation.
  • Stabilized formula reduces chlorine loss from UV exposure.
  • Suitable for various dosing methods (dispensers, feeders, skimmers).
  • Helps maintain safe water by eliminating bacteria and harmful organisms.
  • Minimal impact on water pH, simplifying overall water balance.

Cons

  • Requires regular monitoring of chlorine and pH levels.
  • Initial shock dose needed for freshly filled hot tubs.
  • Dispenser needs to be removed during hot tub use.
  • Effectiveness can vary based on water flow and temperature.
  • Tablets may not be suitable for all types of pool or spa systems.

Setup, Compatibility & Care

Setup:

  1. Ensure your water's pH level is within the ideal range of 7.2 – 7.6. Adjust using pH increaser or decreaser products if necessary.
  2. For hot tubs, a shock dose of 50mg/l (ppm) for 1 hour or 20mg/l (ppm) for 2 hours is recommended for newly filled tubs.

Application Methods:

  • Floating Dispenser: Fill the dispenser with tablets. Adjust the dispenser's aperture or the number of tablets to achieve the target free chlorine range (3-5 mg/l for hot tubs, 1-3 mg/l for pools). Remove the dispenser from the hot tub during bathing.
  • Chemical Feeders: Fill the dispenser according to the manufacturer's instructions. Regulate the flow to maintain the required chlorine levels.
  • Skimmer Baskets: Place tablets directly into the skimmer basket for slow release.

Compatibility:

These tablets are compatible with most standard hot tubs and swimming pool systems, including those using floating dispensers, chemical feeders, and skimmer baskets. They are specifically designed for regular dosing.

Care:

Store tablets in a cool, dry place away from direct sunlight and incompatible materials. Keep the container tightly closed when not in use. Always handle with dry hands and avoid mixing with other chemicals.
