How much do you know about the Algicide?

When your pool is idle for a while, it may grow algae, which may cause the water to turn green,

or it may attach to the water level near the pool wall, which is not good looking. If you want to swim but the pool water is in this state, it will cause a bad effect to your body. The algae needs to be removed and then wait until the water is clear. Algae can consume free chlorine in the pool, making the water cloudy and provide a place for bacteria to grow, so, remember to check your pool frequently. You’d better use some algicide in usual, and once the algae growth is detected, use shock to remove them.

Common pool algae including:

Green algae: A green, single-celled organism that is also common in swimming pools. Floating in the pool water will make the water green, clinging to the wall or bottom of the pool will make them slippery.

Cyanobacteria: Usually blue or green floating filaments, which are prone to algal blooms when the environment is suitable, that is, algae grow suddenly in large areas and are more tolerant to algicides than green algae.

Yellow algae: Also known as mustard algae, which love shade environment. It will grow on the walls of the pool, producing scattered yellow, gold, or brown-green spots.

Black algae: This is the most annoying and hardest to remove of all swimming pool algae. Black, brown, blue-black spots or streaks about the size of an eraser head appear on the walls of the pool. Black algae are very resistant to algaecides and can usually only be eliminated with a high concentration of chlorine shock and careful scrubbing. Or rub a TCCA tablet into a tile crack.

What’s the pros and cons about the algicide?

The killing algae principle of algaecide is by disrupting the physiological functions of algae, such as cell division and photosynthesis, to make them die. Algaecide is usually very slow to kill algae, so it is mainly used to inhibit algae growth, to suppress the formation of algae, it is necessary to maintain the level of free chlorine at 1-3 ppm, and add some algaecide to prevent the formation of algae. If the algae have started to grow, usually use chlorine shock method to remove them, which is more rapid and more certain effect.The killing algae principle of algaecide is by disrupting the physiological functions of algae, such as cell division and photosynthesis, to make them die.

Chelated copper: It is usually a blue or blue-purple liquid with an ammonia odor. The advantage is that the cost is very low while the effect is very good. Additionally, it can be used as an algaecide in winter to prevent the breeding of algae in the swimming pool during winter. The downside is that if you accidentally drink a sip of pool water, it can have a certain toxic effect. Meanwhile it may cause scaling and lead to precipitation. At the same time, it will take 24 hours or even a weak to take effect.

Polyquaternary ammonium salt algaecide: WSCP and APCA are two common polyquaternary ammonium salt algaecides, and their characteristics and application methods are almost the same, showing as light yellow-wish liquid. Usually added for preventing algae growth. In the meantime, they do not cause foam, scale or coloring, and, the most importantly, not toxic. If the algae has started to bloom, you need to add shock with WSCP or APCA.
