Cloudy Water

Blue cloudy water – what are the possible causes?

1. Poor water circulation?

o Make sure your filter system is in good mechanical condition.
o Maybe you’re not filtering the water for long enough. If so, run the pump and filter for 24 hours a day until water clears up. Thereafter…
o 10 to 12 hours in summer continuously.
o 6 to 8 hours in winter continuously.
o Use BioGuard Polysheen Blue or Super Clear tablets to speed up the clarifying process.

2. Is pH too high?

o Adjust pH to 7.4-7.6 with BioGuard Lo ‘N Slo. If you are using sanitizers which raise the pH like calcium hypochlorite for routine chlorination, switch to stabilized chlorine. You’ll use less acid.

3. Total alkalinity too high?

o Reduce to the correct level with BioGuard Lo ‘N Slo.

4. Swimmer Wastes (high bather load after pool party)

o Remove non-filterable wastes with BioGuard Burn Out (1 bag per 45,000 l).

1. Possible algae problem?

2. Storm damage? (High levels of debris in pool after storm)

o Check and adjust pH to 7.4-7.6.
o Use BioGuard Burn Out to shock treat the pool (1 bag per 45, 000 l).

o Circulate water for 2 hours on bypass.
