Typically the sand in filters needs to be changed every 5 years.


How can I tell if my pool has a leak?

Simply fill a bucket with pool water and put it in the pool so that the water level of the bucket and the pool are the same. If the water level in the pool is lower than the water level in the bucket after one week, you probably have a leak. This method is relatively reliable, because the condensation behavior is the same in both tanks. PH+ would be glad to provide you with this service.

What can I do if I have algae?

Usually, algae is not hazardous to your health. A lab should analyse your algae, because it can produce substances that could irritate the skin or eyes. Although  algae might not present a health risk, it can make the water cloudy and your pool look dirty, thus negatively impacting your pool enjoyment. Your constant chemical cleaning can reduce the amount of algae in the pool. If that does not help, you should contact a professional cleaning service. PH+ would be glad to provide you with this service.

What can i do if my pool goes green?

The main cause of a green swimming pool are low chlorine levels or ineffective chlorine have allowed green/black algae to flourish. The cure is to superchlorinate and leave the pump running for 24 hours to kill the algae. Brush all surfaces to displodge algae and to improve the circulation of the superchlorinated water. Backwash the filter after 24 hours. Any water haze can be removed with flocculant. If your pool is susceptible to algae use an algaecide monthly. PH+ would be glad to provide you with this service.

Why is my Swimming Pool Cloudy and Milky in appearance?

Many things can cause cloudy water, including unbalanced water and poor filtration. Assuming the problem is water related and not the fault of equipment, the problem could be caused by algae, high levels of total dissolved solids (TDS), body oils, low sanitizer levels, or high PH or calcium hardness levels. shocking usually clears up any cloudiness, especially if the culprit is algae. If shocking does not work use a clarifier to help the filtration do its job. Use a clarifier regularly, following the instructions on the product label. Make sure the clarifier you select is compatible with the sanitization system you are using. PH+ would be glad to provide you with this service.

How often do I need to change the sand in my Filter?

The manufacturer would probably recommend every 5 years. If sand is entering the pool via the inlet valves in the swimming pool, one of the laterals in your filter may be broken or if you have mud balls remove the effected sand and replace it with fresh sand or glass crystals (VIBRIO). If your filter has not been backwashed consistantly mud balls may have formed or the sand may have calcified and is no longer able to filter out dirt. If you have a DE filter the DE may have coagulated or solidified. If you notice hardening of the DE cake remove the grids and clean the elements, following the manufacturers instructions. PH+ would be glad to provide you with this service.

Pool Chemicals Are Dangerous!

All chemicals used to clean and maintain your pool are hazardous to one degree or another, but treated with care they can be used safely and will be your faithful servants.
