GLB Alkalinity Up

Total Alkalinity is the measure of all of the alkaline substances that can be found in your pool or spa. Your main focus when dealing with Total Alkalinity is to measure your calcium carbonate, keeping your calcium carbonate in a safe range will help with the up keep of your pool and much more. Your Total Alkalinity should be keep between 80ppm (parts per million) and 120 ppm. When your Total Alkalinity is in this range it will prevent rapid pH changes in your pool or spa as well. It really helps to stabilize the pH.

If your Total Alkalinity is low there are many things that this could do to your pool or spa. With it being low it can corrode metal parts that are in the pool or spa, for example your steps, hand rails, pumps, etc. It can also stain the pools walls and floors, and make the water green. On top of all that it will also cause your eyes to burn and can cause your pH to bounce seemingly at random.

If your Total Alkalinity is to high it really makes it difficult to adjust the pH levels in the pool or spa. With the Total Alkalinity being to high it can also make your water cloudy and cause the chlorine to lose its effectiveness as a disinfectant. This could also cause your filter and heating elements to get clogged up. So keep in mind that it is very important to keep your Total Alkalinity in the correct range and it will make it a lot easier for you to be able to keep up with the up keep of your pool or spa.



What is pH and how does it affect a pool or spa?

pH scale

pH is the measure of the acidity of the water. The lower the pH the more acidic it is and the higher the pH the more basic it is. Maintaining pH, or potential Hydrogen, is simple and easy when you understand just a few basics. pH ranges from 0-14 with 7 being neutral.

Your pool or spa’s pH should be between 7.2 and 7.6. Your eyes pH is between 7.3 and 7.4, so the closer you are to 7.4 the less burning sensation you will have in your eyes. If your pool or spa’s pH is below 7 then the water becomes more corrosive and will start to wear away your metal components. For example your pump, your heater, and it also removes the plasticizers from the vinyl liner & pits the concrete, etc.

If you pool or spa’s pH is to high then it will start to build up scale. Scale can begin to form on the warmest parts of the pool, so the heater is the first victim. Scale acts as an insulator on the heat exchanger. That can run up the cost of operating your pool because you have to use more natural gas or electricity. And finally the higher the pH is in your pool or spa the less effective your chlorine will be, and the less sanitized it will be.



Why Does My Swimming Pool Get Cloudy

Many factors go into answering this question. Some possible reasons are;

1. Dirty filter or baskets (skimmer & strainer)

2. Not running the filter & pump long enough each day

3. Chemical problem

Lets discuss each.

If you have a sand filter, the sand may need to be replaced or just try getting the proper pool chemical and clean the sand first. Sand should be cleaned several times a season and changed every 3-5 years (this could vary depending on pool and chemical usage). If you have a cartridge filter, make sure you have a clean cartridge. If you have a DE filter, make sure you have enough DE Powder and that the grids are clean. Every time you backwash your DE filter, you should add the recommended amount of DE powder.

A lot of customers only turn their pump on at night. With high heat and humidity, the pool water will always look cloudy. If you have a continuous use pump, your filter system can run 24/7 during the summer. The more you filter the water, the cleaner it is going to be. With a chlorine generator, make sure the unit is in the right function to produce the proper amount of chlorine from salt.

Water chemistry is the most common reason for cloudy water. All these chemicals have to be in the proper range or cloudy water could be the result;

Chlorine reading- 1.5-2.0

PH- 7.4-7.6

Alkalinity- 110PPM

Calcium Hardness- 250 +

Stabilizer- 40 PPM

Please note that based on the chemical system you are using, these recommended readings may vary. If you bring a sample of your pool water to your local Medallion dealer, they can test it and give you the advice you need to eliminate cloudy water.



Why Is My Chlorine Reading Always Low In My Pool

For those of you who occasionally have this problem, here are a few possible reasons. Please remember that this information is generic. Your pool may have different requirements. See your Medallion pool dealer if you have any questions.

The sun will cause Chlorine levels to quickly dissipate if you do not have the proper level of Stabilizer. The proper amount of Stabilizer in your pool water will extend the life of your Chlorine. Cyanuric Acid is the chemical used as a swimming pool stabilizer.

The proper range of Stabilizer using chlorine as the sanitizer, should be in a range of 30-60 PPM (parts per million). For the customers that use Granular Chlorine, that product has no stabilizer built into it. You need to use Cyanuric Acid on a regular basis to extend the life of your chlorine. If you add granular chlorine to your pool in the morning and get a chlorine reading, that reading could be zero in the afternoon due to low stabilizer level.

For customers that use Chlorine tablets, stabilizer is built into the tablet and Cyanuric Acid may not be needed as often. The problem is when a chlorine floater is used and 3” chlorine tablets are placed in the floater, the pool may not be getting enough chlorine or stabilizer because these tablets do not dissolve quickly enough. This will result in algae and almost a zero stabilizer reading.

Using an Automatic Chlorinator with the chlorine tablets inside, will give you a better choice of your pool receiving the proper chlorine level and the proper stabilizer level. It is very important to get your pool water checked on a regular basis for the proper reading of stabilizer.

If you are using a Chlorine Generator (Salt System) the stabilizer level is extremely important. Most Chlorine Generators produce Chlorine at a steady pace without the high and low level spikes you get when using granular. Without the proper Stabilizer level to protect this Chlorine from the sunlight you could be losing it nearly as fast as it is being produced.



How Deep Should My Inground Pool Be?

clock May 5, 2016 07:00 by author medallionpools |

This is a question that is asked the most by the family that is looking into installing an inground swimming pool. The shallow end of the pool has normally been 42” deep with a water depth of about 3’. If you are looking for more depth in the shallow end, 48” panels are available with a water depth of about 3-1/2’.

The deep end of your pool will depend on how you want to use it. Would you like a pool that you could play volleyball in, maybe put up a basketball goal? If so, then you might want to consider a pool with a 5’ deep end. With this type of pool, you can use the whole pool for recreation and be able to touch the bottom without it being over your head.

If you love to dive, then choose a pool with at least an 8’ deep end. With a deep end pool, make sure you understand the length of the shallow end. You are not going to want to dive all the time and will want some pool area you can play in. Depending on the size pool you purchase, some sizes may only have a shallow end that is 6’ in length.

The deep end depth is a choice that will take some consideration. Do you want to dive more or play games more while using your pool? Only you and your family can make that decision. Make sure the pool dealer you are consulting with informs you the floor dimensions of the pool you are considering. Many pool sizes and shapes will offer you the best of both worlds; diving and playing games.
