Best Swimming Pool Algaecides Buying Guide
Before choosing the best swimming pool algaecide you should consider following options:
1. How your pool water is treated: Before choosing an algaecide you should check with your local pool supply store to find out how their water is treated and what they recommend. Most pools are treated with a combination of shock and algaecide.
Shock is used to treat the water and reduce the amount of organic matter, especially dirt and bacteria, in the water. Shock is used most often during the winter months, when the pool is not being used, and also during the spring and fall when the heat of summer has reduced the effectiveness of algaecide.
Algaecides are used to control algae growth and reduce the need for shocking, which reduces the chlorine demand. Algaecides are generally used from late spring to early fall.
2. Type of pool: There are many different types of pools to choose from when building or remodeling. Your choice will depend on your lifestyle, budget and the environment.
Some of the most popular types include in-ground, top-side, semi-private, private and quarry. In-ground pools are a very popular type of pool and are generally considered the most economical. Top-side pools are a good choice if you want a pool but want to keep the cost down.
Semi-private and private pools are good choices if you have a larger budget and want a more secluded pool. Quarry pools are the most unique and are good choices if you want a unique or custom look.
3. Algaecide use: Algaecides are used to control algae growth and reduce the need for shocking, which reduces the chlorine demand.
Higher levels of chlorine in the water cause irritation of the eyes and skin, damage swimsuits and hair, and can potentially cause health problems. There are different types and strengths of algaecides available to meet your pool’s needs.
4. Amount of algae in your pool: Whether there is a lot or a little algae in your pool, you need the right algaecide to control that growth.
People who have pools with little to no algae growth can use a maintenance algaecide for a low chemical demand.
People who have pools with heavy algae growth will need an algaecide with a higher chlorine demand to control that growth.
5. Amount of algae control needed: Most pool owners need a maintenance algaecide, which has a low chemical demand.
Some pool owners need a high-demand algaecide, which has a higher chlorine demand. The strength of the algaecide will depend on the type and amount of algae in your pool.
6. Time when algae control is needed: There are several factors that impact the effectiveness of algaecides. Some of these factors include pool usage, water balance, type and strength of algaecide, amount of algae growth and algae species.
There are times in the year when algae growth is minimal and times when algae growth is very heavy. You need to make sure you are using an algaecide that is compatible with the type and amount of algae in your pool.
7. Water balance: The amount of total dissolved solids (TDS) in the water plays an important role in algaecide use. TDS is the total amount of salts dissolved in water, including calcium and magnesium.
If the TDS level is too high, the algaecide may not be as effective. The TDS level can be determined
