How to Prevent Pool Algae

Tips and tricks on how to keep the pool free from green algae

Several products are effective for preventing pool algae. Here are some common ones

Chlorine

People commonly use chlorine as the most effective sanitizer for pools, as it kills algae and prevents its growth. You can use chlorine in various forms, including liquid chlorine, chlorine tablets, or granular chlorine.

Algaecides

Algaecides are specifically formulated to prevent algae growth in pools. They work by disrupting algae’s ability to photosynthesize and reproduce. There are different types of algaecides available, such as copper-based, quaternary ammonium compounds (quats), and polyquat-based algaecides.

PHMB (Polyhexamethylene Biguanide)

PHMB is a non-chlorine sanitizer that is effective against algae and bacteria. Many people who are sensitive to chlorine or prefer a chlorine-free pool often use it as an alternative.

Enzyme Products

Enzyme-based pool cleaners break down organic contaminants in the water, including oils, lotions, and other substances that can feed algae growth. Additionally, using enzyme products can help prevent algae by removing these organic nutrients from the water.

Clarifiers

Pool clarifiers help remove small particles from the water, making it clearer and reducing the nutrients available for algae growth. While not specifically designed to prevent algae, using a clarifier can indirectly help by improving water quality.

Phosphate Removers

Phosphates are nutrients that algae feed on, so reducing phosphate levels in the pool can help prevent algae growth. Phosphate removers are chemical treatments designed to bind with phosphates in the water, making them easier to remove through filtration.

Routine Shock Treatment

Regularly shocking your pool with a high dose of chlorine can help prevent algae growth by killing off any algae spores that may be present in the water. Shocking also helps oxidize organic contaminants and restore chlorine effectiveness.

When choosing a product for preventing pool algae, consider factors such as your pool’s size, water chemistry, the type of algae you’re trying to prevent, and any personal preferences or sensitivities you may have to certain chemicals. It’s also essential to follow the manufacturer’s instructions for dosage and application to ensure optimal effectiveness and safety.
