Chlorine

clock July 6, 2016 10:00 by author medallionpools |

This is still one of the most commonly used disinfectants in a swimming pool. Several types of Chlorine Compounds are available.

1. Unstabilized Chlorine

A. Calcium Hypochlorite- granular and will not dissolve completely in water. Will tend to leave a lot of residue in the bottom of your pool.

B. This chemical will need to be put into your pool.

C. Stabilizer will also have to be added to extend the life of your chlorine.

2. Stabilized Chlorine

A. Tri-chlor- This is the solid form of chlorine and could be either chlorine tablets ( 3” or 1” ), or chlorine sticks.

B. Di-chlor- this is in granular form and is slow dissolving.

C. This product line has stabilizer built into it.

D. If you use a floater with chlorine tablets, you may need to add some stabilizer because the tablets will not dissolve quickly enough.

Chlorine is susceptible to rapid decomposition from the sun’s ultra-violet rays. In order to improve the effectiveness of chlorine and reduce its loss, the stabilizer or Cyanuric acid level will need to be maintained above 40 PPM. The Free chlorine level of your pool water is what is the most important. That level should be maintained between 1.0 – 2.0 PPM. Your pool could have a chlorine reading and still have algae because the free chlorine level is too low.



What Options Do I Want To Add To My Pool

Now that you have made the decision to install an inground vinyl liner swimming pool, you have many option choices. In the deep end of your pool, you may want to install a Swimout or In Pool Seat. One item would take the place of an 8’ panel and the other a 6’ panel. The Swimout is 8’ in length and you have room to sit in, lean back in and steps to exit the pool. The In Pool Seat is 6’ and designed for two people to sit in. Both of these items extend beyond the pool edge.

All of the above options are also available in a version that is covered by the liner. This gives you a more built in look.

What can you do in the shallow end? Maybe you do not like the normal white entry way step. This step can be replaced by liner steps that can fit into the corner, extend the width of the pool or be placed in the center of the shallow end. The top liner step can also be manufactured larger to make a sun lounger area.

Would you like lighting for your pool? Some manufacturers offer a Dry Niche Light. This light will have a lid like a skimmer and you get to the light bulb by lifting the lid from your pool deck. This type of light will use a regular flood light bulb. A LED version is also now available with over 10 color combinations. The LED light offers a remote just like gas logs might have.

What about pool shape. This is only limited by your imagination. Most liner manufactures now have equipment in place to do just about any size or shape you want. The many different shapes are called by different names from the manufacturers. Names like, Rectangle, Grecian, Lazy L, True L, Freedom Lake, Chesdin, 4’ Radius Corners, 2’ Reverse Radius Corners, etc. You no longer have to settle for the box shape pool. Discuss these many design options with your local Medallion Pool Dealer.



Swimming Pool Equipment Maintenance Tips

Here are just a couple of quick equipment maintenance tips to help keep things running smoothly. Be sure to read your equipment manuals and follow the manufacturers’ recommendations.

If you have a Sand or DE filter you probably have a Multi-Port Value that either attaches to the top of your filter or is mounted on the side of your filter. The handle you push down when you want to change a function has a spring under it which you can’t see. It is a good idea once or twice during the pool season, turn your pump off, push the handle down and spray some type of lubricant under the handle to keep the spring lubricated.

The pump has a lid that has an o-ring either that mounts on the lid or has a grove in the pump it mounts to. This o-ring needs to be lubricated with o-ring lube to help it seal better and make it easier for you to remove the pump lid to clean the strainer basket. If the o-ring does not seal properly, your pump may not prime or the strainer basket may not fill up completely with water. You will notice a lot of air bubbles.

On the pump you also have drain plugs. Most of these drain plugs have a small o-ring. If this o-ring is missing or broken, a lot of air will get into your filtration system and the pump may have a hard time priming or the strainer basket may not fill up with water. Make sure the o-ring is in place. You can wrap a small amount of Teflon tape around the threads and cover that with o-ring lube.

If you have an Automatic Chlorinator, this unit has an o-ring. This o-ring is either mounted in the top of the lid or on the chlorinator itself. This o-ring will wear out and become brittle and may have some small breaks in it. This could cause air leaks. Replace if needed and cover with o-ring lube.



How To Backwash Your Sand Filter

clock June 23, 2016 07:00 by author medallionpools |

These instructions are for a standard sand filter with a multiport valve. Please see your owner’s manual to verify the proper backwashing/cleaning procedure for your particular filter.

It is important to remember that you only need to backwash if the pressure gauge is reading too high or the flow of water from your return into the pool has slowed. While you are backwashing you will need to watch the level of the water to make sure it does not go below the bottom of the skimmer. Re-fill the pool if necessary. If you backwash too much, you will need to chemically re-treat the water. Follow these simple steps to backwash your filter:

1. Turn off the pump.

2. Attach a hose to the backwash port.

3. Clean the skimmer basket.

4. Turn the filter handle to the “backwash” setting (make sure you roll out the backwash hose).

5. Turn the pump on.

6. Let the pump run until the water in the sight glass on the filter is clear. Your water should start clear, then become dirty, then become clear again. This process should take approximately 1 to 1.5 minutes on average.

7. Turn off the pump and set the filter handle to the “rinse” setting then turn on the pump for 20 seconds or until the water coming out is clear.

8. Turn off the pump and return the filter handle to the “filter” setting.

9. Turn on the pump and resume normal use of the pool. The reading on your pressure gauge is now showing the normal reading for your pool.



Factors Affecting Quality Of Pool Water

Here is a list and short descriptions of factors that can affect the quality of your pool water. Please note that all of the information below is generic and will not apply exactly the same way to all pools. Be sure to discuss any questions or concerns with your local pool professional.

BATHING LOAD- The more people that use your pool, the more disinfectant that you will need to control Algae and to properly sanitize your pool.

SUNLIGHT- The warmer the weather, the faster you will lose the residual disinfectant needed in the pool to control bacteria. You can make the residual last longer by maintaining the proper stabilizer level.

WATER TEMPERATURE- most pool chemicals will not last as long in your pool as the water gets warmer. The acceleration is even greater when the water temperature gets above 85 degrees.

WIND & RAIN- When you experience periods of wind & rain, these conditions will carry dust, bacteria and even algae spores into your pool. These items will overwork your current chemicals reducing their ability to properly sanitize your pool.

PH- When the PH level of your water rises, the ability of your pool water to disinfect bacteria will decrease. You need to maintain the PH level in the 7.2-7.6 range.

TOTAL ALKALINITY- When Alkalinity level is below 80 PPM, this will affect the PH level and could cause staining in a plaster pool or result in possible algae growth. When the alkalinity level is too high, above 130 PPM, this could cause cloudy water and scaling.
