How to remove algae stains from pool walls

How to remove algae stains from pool walls

Stain changes the appearance of the pool’s surface and damages the pool. This definition includes ladders, and most pool owners refer to them as stains. Scales are usually colored because they contain metal and dirt. Strictly speaking, leaves are not stains, but calcium carbonate (chalk) deposits on the pool’s surface can be recognized by their milky appearance and rough surface (often called sandpaper).

The stain can be the hair clip’s size or where the pool’s entire surface is dyed.

It is rare to find a pool that does not have a specific descriptive spot, and deciding when or when you will be called is when the pool owner considers it unacceptable.

Types of Algae Stain on Your Pool

There are usually four types of dirt on the swimming pool and the pool’s sidewalls. It confuses your inner mind about exactly what you are looking at when you notice dirt on your poolside. Therefore, you should first check the color type to diagnose the stain.

This stain is commonly found in iron and copper-based pools. You have a corroded copper pipe in your pool water line for the water source.

And this Mattel device also causes dirt. Therefore, if you want to diagnose this stain, apply ascorbic acid-vitamin powder to the color. And it will give you an accurate confirmation of dirt removal or even lightening the stain.

Organic stains are usually green or brown stains. Hence, it is easy to diagnose this stain. It grows when many leaves fall into the pool, leaving a mark on it. 

Therefore, an easy way to identify stains is to increase the chlorine for about a day. Please note that you need to apply chlorine directly. And if it’s organic, if it goes away smoothly.

If calcium’s hardness becomes very high, the calcium level in the pool and the pH balance of water will be imbalanced. It creates white and gray stains around the plaster in the pool. When your pool accumulates this dirt, you need to identify the type of calcium given to you.

There are two types of calcium, calcium carbonate, and calcium silicate, accumulated in the swimming pool. Calcium carbonate is white on the sides, and calcium silicate is grayish-white.

How to remove algae stains from the pool walls

Removing algae from your pool involves several factors. First, ensure your pool’s hygiene, filtration, and circulation systems are all working. Also, check the chemistry of the pool.

 If you do not have a self-cleaning pool, vacuum the pool at least once a week to remove debris. For isolated blue-green algae, treat with granular chlorine. You can also get a paintbrush, smear water with algae, and scrub. If you have floating algae, you need to shock the pool.

First, balance the water in the pool and keep the pH between 7.1 and 7.3. Check the filtration system and pump system, and turn off the heater if there is one that lowers the water temperature. 

Adjust the valve of the pump and operate it for 24 hours. You can stir the algae by turning on the pool cleaner. Get a stiff bristle brush, scrub the pool walls and floor daily, then vacuum the pool. For green water, apply a flocculant to give a shock.

Violently shock the pool to remove floating algae. You should give it enough shock that your pool water is blue/gray. The goal is 30 ppm free chlorine, which requires approximately 2 to 5 kg of impact per 10,000 gallons in the pool. 

The day after the pool’s impact, chemical levels are tested, particularly concerning pH and chlorine. If the chlorine is less than five ppm, you need to shock it again.

Chlorine should be less than five ppm before adding algae pesticides. Once added, polish the sides of the pool and vent when calm.

 If your filtration system is struggling to purify, you can add a cleaner. Chemicals must be tested and rebalanced.

If black algae are spread, polish the algae with enough force to tear off the protective layer. This will help the chemical get into the roots and kill them. 

It’s only on the wall and will shock the pool unless it floats. Add the algae, leave for 2-3 days, brush again, vacuum up debris and backwash the filtration system.

Prevention of pool algae

Controlling chlorine levels is the best way to prevent the explosion of algae growth in the pool. Maintain a good water balance, run a filtration system daily and add algae to the water weekly. 

The alkalinity level should be 100 ppm, the pH should be 7.2, and the cyanuric acid level should be 30-50. These are the best levels to stop the algae before they set. Install it.

You want your water to reverse twice daily completely. Chlorine drops to 2-4 ppm, and water must constantly circulate. Mineral or ozone supplements and UV treatment may also work. If possible, add the following to the water:

Minerals-Copper, silver, and gold are all minerals that slow algae growth. You will get chelated forms of these minerals that prevent them from polluting your pool’s walls, equipment, and floors.

Chitin-Chitin can stop algae growth by cleaning the various pollutants that the algae feed on the water. It also improves the efficiency of filtration systems and pool disinfectants.

Phosphate Remover-Phosphate is a major part of the algae diet. Phosphate levels can rise as fertilizer spills, and leaf debris falls into the pool, and this chemical removes them.

Potassium tetraborate-This chemical prevents algae from turning carbon dioxide into a food source for flowering and diffusion.
