5 Possible Issues That Lead to Cloudy Water in Your Swimming Pool
Here are 5 potential problems (with solutions) that could be causing you pool water to be cloudy.
Potential Problems:
1. Elevated pH levels
2. Inadequate disinfectant quantity
3. Insufficient filtration
4. Presence of limescale caused by hard water
5. Over-stabilization
Treatment Recommendations:
1. Elevated pH levels:
To rectify, utilise hth pH MINUS MICRO-BALLS, a product specifically designed to lower the pH level to a range of 7.0 to 7.4. Follow this by administering a shock chlorination treatment using hth® SHOCK Powder. It is advisable to wait for 24 to 48 hours before using the pool.
2. Inadequate disinfectant quantity:
Adjust the pH level to 7.0 and subsequently perform a shock chlorination treatment using hth® SHOCK® Powder if your pool is chlorine-treated. For bromine-treated pools, employ hth® BROME ACTIVATOR instead. Allow 24 to 48 hours before utilising the pool. If you have a sand filter, incorporate the flocculating cartridge hth REGULARFLOC into the skimmer and remember to rinse the filter. Keep the filtration running continuously for 24 to 48 hours.
3. Insufficient filtration:
Enhance the filtration process by increasing the duration. Calculate the filtration time per day using the formula: Filtration time per day = Water temperature (T°) / 2 + 1 hour. For example, if the temperature is 24°, the calculation would be 24/2 + 1 = 13 hours. For further guidance on optimal filtration time, refer to our expert tips. If your pool employs a sand filter, introduce the flocculating cartridge hth REGULARFLOC into the skimmer.
4. Presence of limescale (hard water):
Maintain the pH level within the range of 7.0 to a maximum of 7.2. If your pool has a sand filter, you should also use the flocculating cartridge hth REGULARFLOC in the skimmer.
5. Over-stabilization:
Consult a pool specialist to assess the stabiliser content, ensuring it remains below 75 mg/l. If the stabiliser level exceeds this threshold, partial or complete draining of the pool is necessary. After refilling, adjust the pH to a range of 7.0 to 7.4. Furthermore, switch to using hth STICK, a product containing unstabilized chlorine (calcium hypochlorite) if there are no other substances in the skimmer.
