Pool algaecide, what is it for?
The algaecide is a pool chemical used to prevent and control algae growth.
Algae can cause pool water to become green, cloudy and slippery, in addition to being a health risk and making pool maintenance difficult. Using algaecide helps keep the water clear and safe for swimming.
How to use pool algaecide
- Read the algaecide manufacturer's instructions to determine the correct dosage for the size of your pool.
- Make sure the filtration system is working appropriately.
- If it is the first time you use algaecide or if there is a large amount of algae, carry out a shock treatment following the manufacturer's instructions.
- Add the algaecide to a container with water and distribute it evenly over the pool in the recommended doses.
- Apply a maintenance dose weekly or as recommended by the manufacturer to prevent algae growth.
- After adding the algaecide, analyzes pool water and regulates the pH level as needed.
- Keep the filtration system running for at least 24 hours after applying the algaecide to ensure good distribution and product effectiveness.
- Don't mix algaecide with other chemicals, such as chlorine or clarifiers, unless specifically indicated in the instructions.
- Store the algaecide in a cool, dry place, out of the reach of children and pets.
Good use of algaecide will help you keep a pool clean, clear and safe for everyone!
Types of pool algae
Before applying your algaecide, it is essential that you know what you are facing by identifying the type of algae in the pool, since each one is combated in a different way and there are algae that can resprout quickly, becoming a persistent problem.
Types of algae in swimming pools:
- Green algae: known as chlorophytes, they are cyanobacteria that obtain their green color from chlorophyll. This type of algae reproduces quickly, especially when chlorine levels in the pool are insufficient.
Identification: The pool can go from slightly cloudy to olive green in a single day due to the rapid multiplication of these algae.
- Yellow algae, also called mustard algae, often look like pollen or clumpy sand.
Identification: They accumulate in the corners and at the bottom of the pool, forming visible yellow deposits.
- black algae. Although not true algae, these are cyanobacteria that appear as black dots on rough pool surfaces.
Identification: These algae are highly resistant to chlorine due to their deep roots in the walls of the pool, making them difficult to remove.
- Pink Slime: It is not an algae, but a bacteria that accumulates around the components of the pool.
Identification: Appears as a pink sludge and should be treated quickly to avoid swimming in an environment contaminated by bacteria.
How much and when to put algaecide in the pool
The amount of algaecide What you need depends on the type of algaecide, its format and the size of your pool. The instructions will usually tell you the exact amount, but here are some general guidelines!
The dose is usually 1 liter of algaecide per 50,000 liters (50 m³) of water, although the maintenance dose It is usually 250 ml for every 50,000 liters (50 m³) of water, applied weekly.
Regarding when to use algaecideInitially, if there is a visible algae problem (green or cloudy water), perform a shock treatment. Then apply the algaecide once a week to prevent algae growth. Additionally, before and after periods of intense use you can also use it.
Types of algaecide for swimming pools
Proper pool maintenance is essential to ensure a safe and enjoyable swimming space. A crucial part of this maintenance is the prevention and control of algae, which can make the pool an unhealthy and attractive environment.
To deal with this problem, algaecides are used, and there are different types available on the market, each with its own characteristics, advantages and disadvantages. The most common are copper-based algaecides and quaternary algaecides and below we detail more about them:
- Copper-based algaecides: These algaecides are effective in eliminating algae already present and act powerfully against various yellow algae. A disadvantage is that the precise amount must be used to avoid blue stains on pool surfaces.
- Quaternary algaecides: Quaternary algaecides are a safer option than copper-based algaecides as they do not cause stains in the pool. They are effective in preventing algae growth and, if used in proper amounts, do not cause foam in the water.
Anti-algae for salt pools and polyester/liner pools
Anti-algae for salt pools and polyester/liner pools must be copper-free agicides.
These are formulated to prevent the formation and development of algae in pools with polyester liners or liners and in those that use irrigation systems. salt chlorination. Its composition includes surfactant compounds that provide a high bactericidal, algaecide and fungicide power. It is advisable to apply the product preferably at dusk and when there are no bathers in the water.
In addition, other of its functions must be to clarify the water thanks to its flocculating capacity and prevent the appearance of limescale. It should help keep the electrodes in good condition, improve the chlorine generation process and extend the useful life of the salt chlorinator. Ideally, the formulation should be non-foaming, which prevents foaming.
