FAQ

The green in you pool is a living organism known as algae. The chlorine/bromine levels in the water would have dropped below the correct dosage, making the environment inhabitable for the algae to grow. Dramatic changes in weather and temperature can also be a contributing factor.

To help prevent your pool turning green it is important to keep your PH and Chlorine at the correct levels. This can be tested using testing strips or tablets.The PH should be measuring between 7.2 and 7.6 and chlorine should be 3ppm* or higher. As an added preventative an algeacide should be added to the water, this can be dosed manually on a weekly basis or at the start of the season. During periods of hot or changeable weather, or if the pool is experiencing heavey bathing loads, it is important to keep a closer eye on the chemical balance of the pool.

*PPM= parts per million

When a pool goes green it is important to kill the algae completely, this is done by using a shock or unstabilsed chlorine. Once the algae is dead it should settle at the bottom of the pool as a fine dust. This will need to be vacuumed to waste and not recirculater through the filter.

If your above ground pool has gone green, you should use the same chemicals, however vacuuming the debris may be more difficult. In some cases it is often easier to empty the pool and refill.

There are various ways of testing the chemical levels in your pool or spa. The most popular are the testing strips, and testing tablets. The strips are simply dipped into the water and by using colour comparison a reading can be obtained. a more accurate method of testing is to use test tablets, working on the same basis of colour comparison it is easier to get a cleare reading.
