Doheny's Super Algaecide Plus - Pro-Grade Algae Control

In this review of Doheny's Super Algaecide Plus the bottom line is simple: this is a bulk, pro-grade copper algaecide for pool owners who need reliable, swim-safe control of most algae types. It shines when used as a preventive or recovery treatment because the formula contains 7.1% chelated copper, which the manufacturer says reduces staining while providing long-lasting algae-fighting power. The product comes in a large 12 x 40oz pack, so it is aimed at people who prefer buying in bulk and minimizing repeat purchases.

Key Features

• High copper concentration: The 7.1% chelated copper offers sustained algae control that works on many common algae strains.
• Stain-reducing formula: Chelated copper is intended to lower the risk of copper staining while still delivering effective treatment.
• Swim-safe on contact: The label notes the pool is safe to swim in immediately after use, which simplifies post-treatment planning.
• Non-foaming, clear finish: The product will not foam or cloud the water, helping preserve crystal clear water in most climates.
• Simple dosing: Initial dose is 4 oz per 10,000 gallons and maintenance is 2 oz per 10,000 gallons, making ongoing care straightforward.
• Bulk value: Twelve 40 oz bottles give a total of 480 oz so users who maintain multiple pools or prefer stockpiling get better value.

Who It's For

This is a practical choice for residential pool owners, property managers, or service techs who regularly treat medium to large pools and want a reliable, easy-to-measure algaecide. The bulk 12-pack suits people who prefer to reduce reorder frequency and who already manage water balance with chlorine or other sanitizers.

It is less suitable for someone who needs a non-copper alternative or who treats very small water features where precise microdoses are required. Also, users concerned about copper accumulation or very sensitive surfaces should consult guidance before routine use.
