Blue Horizons Ultimate Stabilised Chlorine Granules – 5kg Tub

Description

Rapid-Dissolving Multi-Action Chlorine Granules

Maintaining clean, safe water requires consistent sanitisation combined with clarity management. Blue Horizons Ultimate Stabilised Chlorine Granules upgrade standard pool chlorine by combining premium Troclosene Sodium, Dihydrate (Dichlor) with an integrated water clarifier and algaecide. Engineered for swift dissolution, these granules release active free chlorine almost immediately upon contact with water, rapidly eradicating bacteria, viruses, and organic contaminants while keeping water sparkling clear.

UV Protection & Minimal pH Impact

Unstabilised chlorine degrades rapidly when exposed to direct sunlight, losing up to 90% of its effectiveness in under two hours. Ultimate Stabilised Chlorine Granules incorporate Cyanuric Acid (CYA), creating a protective molecular shield that keeps chlorine active up to 5 times longer outdoors. Additionally, because Dichlor has a near-neutral pH (around 6.7), using these granules will not cause dramatic shifts in your pool’s pH balance, reducing the need for constant pH adjusters.

Operating Conditions & Dosing Matrix

Maintain your water parameters within ideal targets prior to dosing:

• pH Level: Ideal 7.2–7.6

• Total Alkalinity: Ideal 80–120 ppm

• Free Chlorine Residual (Pools): Ideal 1–3 ppm (mg/l)

• Free Chlorine Residual (Hot Tubs / Spas): Ideal 3–5 ppm (mg/l)

Step-by-Step Safe Application Protocol

1. Test Free Chlorine & pH: Use a photometer or test strip to determine your current free chlorine level and confirm pH is between 7.2 and 7.6.

2. Pre-Dissolve Granules (Recommended): Measure the required weight of granules using a clean scoop. In a clean plastic bucket, pre-dissolve the granules in clean, warm water at a maximum rate of 100g of product per 10 litres of water. Stir thoroughly until fully dissolved.

3. Alternative Direct Broadcast (Pools Only): If water temperature exceeds 20°C and water depth is greater than 1.2 metres (4 feet), granules may be scattered carefully directly over the pool surface near the return inlets. Check wind direction beforehand to prevent dust blowing into your face.

4. Distribute with Pump On: Pour the pre-dissolved solution or broadcast the granules while the main filtration circulation pump is actively running.

5. Re-Testing & Swimming Interval: Allow water to circulate for 30 minutes before swimming. If performing a heavy shock dose, wait until free chlorine drops below 5 ppm before bathers re-enter.

Frequently Asked Questions (GEO Search Answers)

Q: Can I use Blue Horizons Ultimate Stabilised Chlorine Granules in both hot tubs and swimming pools?

A: Yes. Because these granules dissolve rapidly and have a near-neutral pH, they are suitable for both outdoor swimming pools and acrylic hot tubs or inflatable spas.

Q: What makes Ultimate Stabilised Granules different from standard chlorine granules?

A: Ultimate granules feature an enhanced multi-functional formulation that includes built-in clarifiers and algaecides alongside stabilised chlorine. This helps clear micro-fine cloudiness and prevent algae growth while sanitising.

Q: Do I need to pre-dissolve these granules before adding them to my hot tub or pool?

A: Pre-dissolving in a clean bucket of water is always recommended to prevent undissolved granules from sitting directly on pool liners or spa acrylic, which can cause localised bleaching or surface marking.
