Main types of pool algae

During the months of July and August, algae can be a very big problem for swimming pool owners. With owners often avoiding their pools during the colder month’s inconsistency in a pool’s sanitizer levels often change and algae can appear. The different types of algae can be found below.

About Algae

Algae is a single-celled plant form. It utilizes the process of photosynthesis to manufacture its own food and comes in very wide variety of colors and forms making it adaptable to almost any condition. Due to algae’s microscopic size, it takes literally millions of these plants to accumulate to be noticed by the naked eye.

Green Algae

The most common form of algae in swimming pools is “green” algae.  Green algae (varies in color from blue-green to yellow-green to dark-green) can be free floating in the water (turning the water a hazy-green) or can be wall-clinging (patches of green). Green algae can be treated fairly simply with the right amount of brushing, shocking, and algaecide.

Treatment:  Have water properly analyzed to ensure PH is at proper levels and balance the pool water. Pools treated with chlorine should be brushed thoroughly, then shocked, raising the chlorine levels above 30,000 ppm.  Also, add a strong dose of Algaecide 60 to the water. Continue to check the pool’s filtration throughout this process to ensure proper water flow. You may have to repeat this process a few times in order to completely eradicate the algae.

Black Algae

“Black Algae” (actually blue-green algae) forms in cracks and crevices on pool surfaces, especially plaster finishes. Black algae normally grows in shady areas of the pool. Black algae is more typically found in concrete or plaster finished pools because of their rough surfaces. It is known for a heavy slime layer and “skeletal growths” that make it impervious to normal chlorine levels.  Black algae usually doesn’t have any effect on water clarity, it just makes your pool appear to have black spots on the surface.

Treatment:  Have water properly analyzed and balanced. Prior to and during treatment, the algae MUST be thoroughly brushed in order to “break open” the slime layer.  Failure to do this critical step will prevent the treatment from working.  Shock the pool very aggressively and continue to brush the black algae. Add substantial amounts of algaecide 60.

Mustard Algae

Mustard algae is a chlorine-resistant form of green algae (yellow-green to brown in color). It often resembles dirt or sand on the bottom or sides of a pool.

Treatment:  Same as black algae.

In certain cases, when a pool is full of algae, the algae must be vacuumed directly out of the pool. This can be accomplished by brushing the algae off the walls, then adding a ‘floc’ to the water, which coagulates the algae and causes it to settle. Once it settles, it should vacuumed directly out of the pool. When attempting to floc a pool, follow the directions on the bottle very carefully.

Good luck and happy swimming!

Irritated Eyes primarily caused by Chlorine?

Irritated eyes

We’ve seen it happen quite often:

- Children coming out of the pool rubbing their eyes

- Parents claiming that it’s definitely because of an excess of chlorine in the pool.

- Consequently, the poor child is not allowed to go into the pool for the rest of the day

 

This belief that there is an excess of chlorine in the pool is in fact myth! In fact, it’s due to a couple of factors:

First, it is the fact that water in general, regardless of being chlorinated or not, will cause dryness in our eyes and thus cause irritation.

Second, it’s the pH level of our pools. When the pH levels of our pools stray too far from the body’s natural pH balance of 7.4-7.6, it can cause irritation.

Finally, it is the presence of chloramines in the pool that can cause irritation. Chloramines form when chlorine combines with what comes out of or washes off the swimmers’ body (sweat, urine, personal care products etc.).

The truth is that chlorine reacts with sweat, body oils and cosmetics to form products that are irritating and make things worse for the swimmer, forming chloramines.

It is then advised for the benefit of our own pools and those who use it, here are hygiene tips:

- Shower before getting into the pool. Each unshowered swimmer adds their dirt, body oil and sweat to the pool!

- Remember to take the kids out for bathroom breaks often so the pool is kept free from any unwanted accidents that chlorine cannot deal with

- Make sure there is the right amount of chlorine in the pool as it in fact is your first line of defence that can make swimmers sick. It guards against bacteria and viruses that can cause conjunctivitis, stomach upset, swimmer’s ear and irritated skin. If you’re unsure of your pH and chlorine levels in your pool, you can order 6 in 1 test strips or drop in with your water to our store for a free test.

Myths: All about Swimming

Myths – everyone knows them, everyone talks about them. But what is right and what is wrong?

Myth 1: You don’t get sunburnt in the waterMyth Vs Reality
This prejudice needs to be eliminated as the exact opposite is the case. Sun rays can reach up to one meter into the water. Apart from them reaching you through the water, sun rays are reflected from the water surface and their force is many times stronger. This mainly affects parts of the body above the water line, so regular sunscreen application is a must.

Myth 2: Do not go into the water with a full stomach
Doesn’t this remind you of your parents’ warnings? “Swimming with a full stomach will give you stomach cramps!” Is it true? There is no increased risk for people who go swimming after eating. However, we can note that a full stomach prevents swimmers from performing at their best level as the body is busy with the digestive process of the stomach.

Myth 3: Chlorine ‘roughens’ your hair and turns blonde hair green
Chlorine does in fact have a “roughening” effect on hair. Its specific effect on your hair depends on the type of chlorine, the level of chlorine in the water and how long your hair is in contact with the chlorine. After swimming in a swimming pool hair should be rinsed out with clean water to prevent the hair from roughening too much. Naturally blond or coloured hair can take on a greenish shade. This is not due to the chlorine in the pool, but because of the copper content in the water, which binds with the hair proteins. Fair-haired swimmers might consider putting a bathing cap on or using specific shampoos that assist in removing copper.

Myth 4: Swimming is bad for people with asthma
This is not true! Experts actually recommend swimming for asthma patients. It is one of the best and healthiest forms of exercise that people who suffer from asthma can do. While swimming, they breathe in the air near the surface of the water that is warmer and more humid (moist) in comparison to normal air. It also helps increase the volume of the lungs and its functions and is a healthy form of exercise for people of all ages.

Myth 5: Swimming is good for the back
Basically, all experts agree. Swimming strengthens the back muscles and prevents painful tension and poor posture. But swimming for people who already have back problems, especially with the spine, can rather harm the body. Especially inexperienced swimmers, who stretch their neck backwards to breathe better, put too much pressure on their cervical vertebrae and neck muscles and thereby trigger spasms and tension.

5 tips for things to do to keep your skin look & feel great after swimming

Yes we love swimming but no we don’t like our after-swimming skin: itchy, red, dry, cracked or even wrinkled.

Woman with soft skin after swimming

The following five tips can help you keep a soft skin even if you’re swimming a lot.

1)     It may seem a little obvious but the first skin-care tip we can give you is to drink water! Before and after swimming. Why? Because dehydration make it harder to restore your body’s natural moisture.

2)     Right after a good swimming session, take a long bath or shower and put loads of moisturizer on your skin. Most of the cream will be absorbed and your skin will thank you for this.

3)     Wash your swimming costume with fresh water immediately after you come out of the pool to get rid of the chlorine.

4)     If, after your shower,  your skin is still:

  • Itchy or red = Put some ice cubes in a clean towel and rub it over your skin to reduce the itchiness or redness.
  • Dry = instead of applying a simple moisturizing cream, try Baby Oil or Vaseline.

5)     Supplement your diet with nutrients rich in vitamin E and C. Whilst vitamin C is an excellent antioxidant, vitamin E improves the skin’s moisture retention capability.

If your skin often feels irritated after swimming, try changing the type of chemicals you use for your pool maintenance. Try our Soft Swim range for example; this is a revolutionary and very skin friendly mineral pool maintenance range.

Also please note that the chemical balance and cleanliness of your pool is an important factor in maintaining skin health. See one of our previous blogs such as the Four Easy Cleaning Steps for your pool for some useful tips.
