Yes. Shocking your pool before closing helps eliminate bacteria and organic matter that can cause cloudy or green water by spring.

Here at ePoolSupply, we like to follow the manufacturer’s recommendations. For most pool equipment, the rule of thumb is an hour at full speed for every 10 degrees it is outside. Here in Phoenix, the Arizona heat can be brutal on your pool. The best thing to do is to run your pool anywhere from 9 to 11 hours a day. If you are using a variable speed pump, 8 hours should be at full speed and the rest of the time can fluctuate to ensure complete circulation of the water in your pool.

It is recommended to clean your skimmer and pump baskets at least once a week. If you have an abundance of trees or any debris around your pool, then you may have to increase the number of times you clean each week. After storms or high winds, it is recommended to clean your skimmers and pool pump baskets to ensure the best possible cleaning.

It is recommended to drain your pool water about every 5 years. Depending on usage and location this may vary but overall, this is the optimal time to change the water out to ensure proper chemical balancing.

It is always recommended to read the label on your chemicals to find the best time frame on when it is safe to enter your pool. Each chemical’s time will vary, but typically, each is about 24 hours. Make sure to consult the chemical’s safety label for more information.

Each filter has its own “rule of thumb” for backwashing. One way to know that it is time to backwash your filter is when you see an increase of pressure of 10 psi on your filter pressure gauge. If you happen to have a Sand filter, it is recommended to backwash once a week in the summertime and at least once a month in the winter season. If you happen to have a DE filter, it is recommended that at least once a month to backwash and replace your DE. It is also recommended to clean your DE filter quarterly.

The ideal PH level for pools is 7.5. pH measures the acidity of the water in your pool. If the pH is above 7, the water is basic and still fine to swim. However, if the pH is below 7 the water is acidic. The optimum pH for pool water is 7.5 since human eyes and mucous membranes have the same pH. A pH of 7.4 also gives good chlorine disinfection. Make sure to check your pH balance at least once a month to ensure the quality of your water.

Yes! It is very important to take the time once a week to brush your pool. Even with an in-floor cleaning system or a pool vacuum, there are many spots in your pool that do not get clean. It is important to make one full run around your pool with your brush to ensure that the walls and tile lines remain clean. This will help with the overall distribution of the pool chemicals as well as keeping the surface clean.

Yes! Pool chemicals can go bad! It is very important to follow all the storage rules supplied on each package to ensure the items are stored properly and away from any children or pets. The first step in storing your chemicals safely is reading and understanding the directions on each chemical in your arsenal. Each one has its own chemical compound and expected shelf life which could be affected by many different factors. Moisture and humidity are some of the detrimental forces at play along with direct sunlight. Be sure to store the items with the lids and caps secured tightly in a well ventilated, cool, and dry area to prevent dangerous fumes and rapid deterioration. Pay close attention to expiration dates and replace chemicals as needed. DO NOT USE EXPIRED CHEMICALS!

From time to time it is important to shock (super-chlorinate) your pool. This can help with fighting algae and keeping your minerals in the water at their proper labels. A good rule of thumb is to super chlorinate bi-weekly in the summertime and about every month or so during the winter months. This will keep your pool at the optimal swimming level and keep your water looking fresh and clean!

It is always a good idea to test your water at least once a week. This will give you an accurate reading of the chemicals in your pool and will give you a chance to stay on top of keeping it clean! By understanding the difference between your minerals in your water, you can accurately add or remove chemicals as needed to ensure the pool is safe to swim.

Calcium hardness is defined as the measure of how hard or soft your pool water is. It also measures the amount of dissolved calcium and magnesium in your swimming pool. Just like pH and total alkalinity, it’s important to keep the calcium hardness balanced to prevent your pool water from becoming corrosive or scaling. The ideal calcium hardness range for pools is 150-400ppm.

In short, yes, a saltwater pool will require chlorine. It will require much less than your standard chlorine pool but will still require chlorine to balance properly.
