Overview

E-Z Clor describes its algaecides as "an extra layer of pool protection" for preventing and killing all types of algae. The line includes non-metallic quaternary products, copper-based products, and one chlorine-based granule.

Algaecide Plus is a 60% polymeric quaternary ammonium (polyquat) product stated as non-foaming and compatible with salt chlorine generators. Algaecide Concentrate is a 50% alkyl dimethyl benzyl ammonium chloride (quat) that the manufacturer says also improves filter operation. Super Green Algaecide (23.09% copper ethanolamine complex), Super Black Algaecide (9.5% copper ethanolamine complex plus 26.3% quat), and 3-Month Algaecide (10% copper triethanolamine complex, 90-day prevention) are the copper-containing options.

Granular Algae Out is 99% trichloro-s-triazinetrione (stabilized trichlor; adds cyanuric acid) with 90% available chlorine, positioned by the manufacturer as a spot treatment for black algae on plaster or white aggregate surfaces.
