Description

Pond Pro® ProClear Algaecide - NSF/ANSI Standard 60 Certified For Drinking Water

Discover the power of ProClear Algaecide, a premium Canadian-made solution designed specifically for ponds, dugouts, and lagoons. This NSF-60 certified product, ProClear, helps keep your water clear and free of algae. Expertly formulated to target and eliminate algae. Its easy-to-use formula makes algae treatment and prevention simple and cost-effective, helping maintain pristine water quality in Canada.

Experts recommend using ProClear Algaecide preventatively to save on labour and costs. By treating algae before it blooms, you can avoid the significantly higher costs of reactive treatments, which can be 2-3 times more expensive. Reactive treatments also require stronger chemical concentrations, which can be harsh on the water and potentially harmful to the ecosystem. ProClear is an effective solution to keep your water algae-free.

ProClear is NSF/ANSI Standard 60 Certified for use as a drinking water treatment chemical where applicable and when used according to the label.

This product will not ship during freezing temperatures.

Important: ProClear is not recommended for ponds less than 50,000 US gallons. For smaller ponds, consider Pond Pro® Green Pond Clarifier.

Algae Management for Larger Waterbodies

ProClear is intended for larger closed waterbodies that require algae management. Apply it preventatively or to manage existing algae, following the product label and site conditions.

When fish are present, carefully control application rates. Do not exceed 3 L of ProClear per 1,000,000 US gallons of water.

Application Instructions

Sprayer Application

Apply ProClear using a sprayer. When targeting filamentous algae, spray the shoreline and extend treatment about 30–50 ft into the water.

To help prevent clogging, dilute ProClear before application. A general starting ratio is 3 parts water to 1 part ProClear, although you may need to adjust the dilution depending on the sprayer used.

Do not exceed 3 L of ProClear per 1,000,000 US gallons of water when fish are present.

In small ponds with fish, the supplied product directions state a rate of 1 mL per 1,000 L of water.

Small Pond Rate Without Fish

For small ponds without fish, the supplied directions state 25 mL per 1,000 L of water.

ProClear is not recommended for ponds less than 50,000 US gallons. For smaller ponds, consider Pond Pro® Green Pond Clarifier.

    Posted by Alice on 5th Jul 2026

    My husband used this product for our small goldfish pond. He said it works great if you follow the instructions. Next year he will be using it in the beginning of the season, before any of the algae starts to grow. Happy

    It works

    Posted by CeeCee22 on 17th Jun 2026

    It took a few applications. My pond is now clear, and the algae are almost eliminated. I will continue to work on the pond until the algae are fully eliminated. My water plants are OK.
