BioGuard Banish

$3999

⚠ 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.

When to Use

  • One bottle at the start of the season to boost the pool’s immunity
  • Once per week to prevent algae growth
  • Can be applied to the pool during or after shocking (most algaecides are compromised by high chlorine levels, but not Banish!)

 

When Not to Use Banish

  • When your pool has an ionizer
  • To get rid of visible algae (always shock and kill algae first with BurnOut, BurnOut3 or Power Chlor, then use Banish to keep algae away)
