Zinc Anode

clock June 15, 2017 07:00 by author medallionpools |

The in-line zinc anode is attached to the bonding wire, thereby protecting all metal parts (heaters, lights, rails, etc.) from galvanic corrosion. Zinc anodes will sacrifice themselves and corrode before all other metals in the pool. Zinc anodes need to be replaced approximately every 4-5 years on average.  Many factors can affect how quickly it will need to be replaced.  We have encountered some pools where the zinc anode had to be replaced every year.

Any time you have different metals (copper, stainless steel, etc.) in a salt water pool, you create a battery. Some amount of current flows between the metals. The electrons that make up the current are supplied by one of the metals, giving up bits of itself in the form of metal ions to the pool water. This is called galvanic corrosion. Galvanic corrosion causes plaster discoloration and metal erosion. The best way to inhibit the effect of galvanic corrosion is to use a zinc anode. Zinc is a metal that gives up its metal ions faster than other metals in the pool. In other words, the zinc anode will erode instead of other metals (pool light, rails, heater, light niche, ladder, etc.). The zinc ions will not discolor the pool plaster. The zinc anode should be replaced after half of it has eroded.

Galvanic corrosion can also occur pools that do not use salt water. Any stray electrical current around the pool area can cause it. Also, many localities are now requiring that the pool water be bonded. The inline zinc anode also performs this function.

Easy Vacuuming On Battery Power

clock June 8, 2017 07:00 by author medallionpools |

Do you get out your telescopic pole, vacuum brush, vacuum hose,and skim vac to clean your pool weekly? Then you have to attach these items and prime the hose before you start to clean your pool. Then when you finish cleaning the pool, you have to turn the pump off, and now backwash your filter then put these items away.

This problem makes you tired just thinking about it. Now, put all those worries behind you. Options are now available that will make it a lot easier for you. Maybe you just have a small area in your pool you want to clean but hate the thought of having to get out all the equipment you would need to vacuum this one area.

Take a look at the battery powered cleaners. All you need is your telescopic pole and a little effort on your part. No hose to prime. No water loss from the pool since you will not have to backwash the filter. The cleaners will attach to the telescopic pole and then you start to vacuum. What you vacuum will go into the mesh net inside the unit. When you finish, just remove the mesh net and clean out the debris.

Just think, no more leaning over the pool to have to prime the hose and then having to install the hose into the skimmer. How many times have you lost your prime from the pump while trying to do this?



Caring For Your Chlorine Generator (Salt System)

clock June 1, 2017 07:00 by author medallionpools |

If you have a chlorine generator (salt system) you know how easy it is to use. By the time you are done reading this you will also know how easy it is to maintain. And all of you that don’t have one will probably being going out to get one after you see the ease of maintenance in taking care of them. Please remember that the following article is for general information purposes only. Refer to your owner’s manual for complete information for the proper maintenance and care of your particular chlorine generator.

Chlorine generators are units that take salt and convert it into liquid chlorine. There are several features that are wonderful about this unit.

Features:

-no chlorine smell

-better for your skin

-savings over the years because you are not buying chlorine tablets or granular chlorine anymore

-easy to install

-easy to use

-easy to take care of

-most have a built in timer so they run automatically

-plus many more options!

Let say your system is already installed. What do you do to maintain it? Most of the higher quality chlorine generators are self cleaning, however, I would recommend still cleaning them once a season to make sure it runs at peak efficiency. Throughout the season you should visit you local pool retailer and purchase a “cell cleaner”. This is a chemical that you can use to flush out the cell of the unit. By using this chemical it will rid your unit of unwanted debris such as calcium build up. Calcium build up is usually visible if you have it, is generally white in color and sticks to the inside of the cell. Some chemical companies have different recommendations so please read the back of the container you buy to see how yours is supposed to be used. The most common method is taking the cell off the pool and mixing the cell cleaner with water and putting it in the cell. You will need two caps to place on each end of the cell to keep the solution from coming out. Shake this up and let it sit for a few hours then rinse it out completely. This is a simple way to clean your unit and takes minimal time and easy to do.

When you winterize your pool you should always remove your cell. If left on the pool the cell could get moisture in it, freeze, and crack over the winter. Most manufacturers will not cover cells that have frozen and been damaged. Once you remove the cell from the pool the easiest thing to do is wrap up the ends of the exposed pipe with a plastic bag or plastic wrap and a rubber band, this will keep anything from getting in the pipes. Make sure the cell is completely dry and store inside for the winter. That’s it!! It’s that simple!

Now when summer comes around you take about 5 minutes putting the cell back on and your ready to go!



Automatic Chlorinators

The automatic chlorinator is a very efficient way to chlorinate your pool with large or small Trichlor tablets or Bromine slow-dissolving tablets to make sanitizing your pool or spa easy and automatic. If you do not have this unit, your options are;

1. Put the tablets in a floater

2. Put the tablets in the skimmer basket

3. Put the tablets in the pump basket

Any one of these three options will present you with a problem. The use of a floater is the lack of the ability to get the proper amount of chlorine in your pool. Since you do not have water flowing into the floater to dissolve the tablets, your pool water is going to be usually low in chlorine with the result being green water and algae build up.

When you place the tablets into your skimmer basket, they dissolve very quickly and it becomes very difficult to maintain the proper amount of chlorine in the pool. It can also deteriorate your skimmer basket and the seals and o-rings on your pump and filter. If you turn the pump off, chlorine will flow back into your pool causing a white stain in front of your skimmer.

If you place the tablets into your pump basket, they are also dissolving very quickly here and chlorine levels could be too high. This also will cause your pump seal to start leaking and your o-rings to wear out quickly with possible pump damage.

The automatic chlorinator is installed after the filter in the water return line going to the pool. It should be the last thing the water goes through before returning to your pool. These units are completely enclosed systems – no escaping fumes. Simple, trouble-free designs with no special venting required. Top loading makes it easy to add chemicals. You remove the lid and place the tablets inside. There is a control knob with different settings that will let you control the amount of chlorine being released into your pool. Note that every pool is different and you will need to adjust the settings based on your particular pool. Automatic chlorinators save time, reduce manual handling of chemicals and take the work and worry out of keeping your pool sparkling clean and ready to use.



Floating Chlorine Dispensers

Are you using chlorine tablets (1” or 3”) or chlorine sticks in your pool? If you are what are you using to get this chlorine into your pool? You may be using a Floating Chlorine Dispenser or Chlorine Floater.

The Floater, as the word states, floats around your pool and tablets slowly dissolve. You do not have water passing thru it very fast to dissolve the tablets or sticks rapidly. This system may work perfectly well for many small pools, spas, or swim spas. However, once you start getting to mid to large size pools (and occasionally some smaller pools with heavy bather loads), your pool water could become cloudy, algae could grow and the liner could become very slick due to the chlorine being released too slowly. The warmer it gets, the more chlorine demand your pool needs and that demand will be hard to satisfy with a Floater.

If you are having problems maintaining your Chlorine residual with a floater and you want to continue using tablets then take a look at an automatic chlorinator. This unit can be plumbed into your return line which has water flowing through it going back into your pool. You can use either 1” or 3” tablets or chlorine sticks in the Chlorinator. The Chlorinator has a control value on it that can be adjusted. You can regulate the amount of chlorine getting into the pool.
