Frequently Asked Questions
Here’s a few answers to our most common questions.
A professional pool service company can protect the valuable investment that is your pool’s surface through properly working equipment and water chemistry.
Weekly service is essential to maintain a great looking, healthy pool. Consistency is vital to your pool’s overall health.
Commercial swimming pools should be tested at least 3 times a day. Chlorine should be fed continuously through a chemical feeding device to maintain a consistent level.
There are several causes for a cloudy pool. Some causes could be that the pH is not within its proper range, calcium hardness levels are above the ideal range (200 – 400ppm in a gunite pool), there is little to no sanitizer in the water, or the filter needs to be cleaned. Check to make sure chemical levels are within their ideal ranges, then clean your filter.
A commercial pump must run continuously (24hrs a day) on a daily basis to meet daily requirements for filtration.
This indicates that the pool water has not been properly treated. A common cause is high levels of chloramines, formed when chlorine combines with perspiration, body oils, urine and other contaminants brought into the pool by the swimmer.
Most dead animals do not pose a health risk to swimmers. Most germs carried by animals are killed by chlorine within minutes in a well-maintained pool.
The evaporation rate depends on the surface area of the pool, the temperature, and the relative humidity and the wind. “Splash-out” water is probably a much more significant source of water loss than evaporation. You can measure water evaporation in your pool by doing the bucket test. Place a bucket on the pool step and fill it to match the water level of the pool. Over the course of 1 day the bucket will lose water from evaporation and possibly gain water from rainfall at the same rate as your pool. As long as there is no splash-out or backwashing during that time, if the pool level drops more than the bucket level then you have a leak.
Chlorine and pH are the first defense against germs that can make swimmers sick. Swimming pool operators should vigilantly monitor chlorine levels and pH, and make adjustments accordingly. The chlorine level in a pool should ideally be maintained between 2 and 4 parts per million (ppm). The pH should be maintained between 7.2 and 7.8. Keeping the pH in the proper range will help maintain chlorine’s germ-killing power while minimizing skin and eye irritation.
Salinity of 2500-3500 ppm (2,5 – 3,5 g/l) is ideal for many salt systems. This is approximately 1/12th as salty as ocean water, or 1/3rd as salty as a human tear.
Gunite pools require daily, weekly, seasonal, and long-term maintenance.
- Daily – chemical control, addition of water, cleaning debris from the bottom, surface, skimmer baskets, and water line tile.
- Weekly – Stock chemicals, inspect function of pool equipment, cleaning debris from strainer baskets, as well as “daily” requirements.
- Seasonally – proper winterization and opening procedures must be followed.
- Long-term – Re-tiling, plaster (or marbledust), and coping stones should be renovated every 7-15 years.
A commercial pool is drained below the pool returns (approximately 18”-24”) which helps account for winter water accumulation.
