RECOMMENDED TREATMENT
(Treatment based on a 50,000L Pool)
(Treatment based on a 50,000L Pool)
- The only way to reduce the stabiliser level is to drain a portion of pool water.

RECOMMENDED TREATMENT
(Treatment based on a 50,000L Pool)
(Treatment based on a 50,000L Pool)
- Brush the pool walls and steps thoroughly to remove algae from the lining.
- Top up the water level to ensure it is well above the weir.
- Backwash and rinse the pool filter.
- Test the pool water and adjust parameters to the recommended ranges.
- Maintain pH at 7.2 — if pH is low, add Alkalinity Up; if pH is high, add HTH® Dry Acid or HTH® Easy Acid following label instructions.
- In the early evening, shock treat with 3 cups of chlorine or a pouch of HTH® Shock It.
- Note: If the green tint remains after 12 hours, repeat the shock treatment as necessary.
- Run the pool pump and filter continuously for 12 hours to clear debris.
- The following morning, backwash and rinse again to remove accumulated debris.
- If significant debris or cloudiness persists, apply a clarifier such as HTH® Xtreme Flocc, carefully following label directions.
IMPORTANT NOTE: Depending on water condition severity, some or all steps may need to be repeated.
Increase or Decrease TA
Increase or Decrease TA (Total Alkalinity) helps stabilize your pool’s pH levels:
- To increase TA, use a TA increaser (PH Plus).
- To decrease TA, use a pH reducer (like dry acid or PH Minus).
- Balanced TA prevents pH swings, corrosion, and cloudy water.
Increase or Decrease pH Level
Increase or Decrease pH Level to maintain water balance and swimmer comfort:
- To increase pH, use a pH increaser (like soda ash/sodium carbonate).
- To decrease pH, use a pH reducer (like dry acid or muriatic acid).
- Balanced pH (7.2–7.6) prevents irritation, scaling, and equipment damage.
Turn green water to blue
Green pool water is usually caused by algae growth due to poor chlorine levels or filtration. Here’s how to turn green water blue again:
- Shock the pool with a chlorine-based pool shock treatment.
- Brush pool walls and floor to remove algae buildup.
- Run the filtration system continuously until the water clears.
- Use an algaecide to kill remaining spores.
- Finish with a clarifier to restore water clarity.
Directions for shock treatment
Follow these directions for effective pool shock treatment:
- Test and balance pH to between 7.2 and 7.6 before shocking.
- Dissolve the shock granules in a bucket of water (if required by product instructions).
- Turn on the pool pump and pour the solution evenly around the pool.
- Use at dusk or evening to reduce chlorine loss from sunlight.
- Shock dosage: 1kg per 50,000 litres (or as per product label).
- Allow pump to run for 8–12 hours continuously after application.
- Do not swim until chlorine levels return to 1–3 ppm.
Remove copper (metals) from pool water
Copper and other metals in pool water can cause stains and greenish discoloration. Here's how to remove them:
- Use a metal remover (e.g., HTH® Metal Remover) to bind and neutralize metals.
- Add 1L per 50,000 litres of pool water, following label directions.
- Run the pump continuously for at least 12 hours after application.
- Use a clarifier after 24 hours to help filter out bound metal particles.
- Test source water (especially borehole water) for metals before refilling.
