Severe algae problems require more than routine maintenance chemicals. When green, mustard, or black algae takes hold, fast action and lasting protection are critical to restoring control of your pool. Poolife AlgaeKill Extreme is a powerful, professional-grade algaecide formulated to kill algae quickly while providing extended protection against regrowth, making it a go-to solution for aggressive algae outbreaks.

Unlike mild preventative algaecides designed for weekly use, AlgaeKill Extreme is built for serious algae conditions. It works rapidly to destroy existing algae colonies while leaving behind residual protection that helps prevent algae from returning. This makes it especially effective for pools that experience recurring blooms, stubborn algae types, or high environmental exposure.

At Benchmark Pool Supply, AlgaeKill Extreme is recommended when standard treatments aren’t enough and algae needs to be knocked down decisively — not just slowed.

Why Some Algae Problems Escalate Quickly

Algae thrives when conditions align: warm water, sunlight, nutrients, and gaps in sanitizer coverage. Once established, algae can spread rapidly across pool surfaces, clog filters, and overwhelm water clarity. Certain algae types, such as mustard and black algae, are particularly resistant and require stronger, targeted treatment.

Simply shocking the pool may kill surface algae but often fails to eliminate deeper growth or prevent regrowth. Poolife AlgaeKill Extreme is designed to break that cycle by attacking algae aggressively and continuing to work after application.

Fast-Acting Formula with Extended Protection

Poolife AlgaeKill Extreme uses a concentrated, non-foaming formula that disperses evenly throughout the pool. It begins killing algae shortly after application and continues working to inhibit future growth. This dual benefit allows pool owners and professionals to regain control quickly while reducing how often algae treatments are needed.

Because it does not foam, it is suitable for use in pools with water features, spas, and high circulation systems when used according to label instructions.

Effective Against Multiple Types of Algae

AlgaeKill Extreme is formulated to combat the most common and stubborn algae problems found in swimming pools, including green algae blooms, mustard algae, and black algae. It can be used as a corrective treatment for active infestations or as a follow-up after shocking to ensure algae is fully eliminated.

Its strength makes it particularly useful in pools with repeated algae history or heavy organic contamination.

Compatible with Most Pool Systems

Poolife AlgaeKill Extreme is designed for use in most residential swimming pools and is compatible with in-ground and above-ground pools alike. It works with chlorine pools, bromine pools, and saltwater pools, and it does not interfere with salt chlorine generators when applied properly.

As with any strong algaecide, proper dosing and circulation are essential to ensure effective treatment and avoid unnecessary chemical buildup.

Application Guidance for Best Results

For best results, add Poolife AlgaeKill Extreme according to the manufacturer’s directions while the pump is running to ensure even distribution. Allow adequate circulation time so the algaecide can reach all affected areas.

In severe cases, brushing pool surfaces before or after treatment can help expose algae to the product and improve effectiveness. Routine filter maintenance after treatment helps remove dead algae and restore water clarity.
