⚠ Product Update – July 2026
BioGuard Banish has been discontinued by the manufacturer.
For customers looking for a replacement, we recommend BioGuard Algae Complete. It utilizes the same proven algae-fighting technology found in Banish, but in a more concentrated formula, allowing you to use less product while achieving excellent results. In addition, Algae Complete incorporates Polyquat technology to deliver broader-spectrum algae protection and enhanced effectiveness, making it a natural upgrade for customers who previously relied on Banish.
BioGuard Banish is our most popular liquid algaecide because nothing does a better job at protecting your pool from algae growth.
