Algae in your water is the last thing a pool owner wants to see. Most people think algaecides are designed get rid of visible algae but they actually are far more effective at preventing algae from ever starting. Banish is our most popular algaecide because nothing does a better job at protecting your pool from algae growth. It’s unique formula has special way of tricking algae to consume it at which point the algae cell can no longer reproduce. That’s like pulling weeds by the root to make sure nothing comes back. Banish has a unique property that builds up the pool’s immune system against algae, like taking vitamins so you don’t get sick, so once you start using it regularly the chances are you may never see algae again. What makes it even better is that you only need to add it once per week, it can go in anytime without any swimming restrictions and one bottle will typically last about 2 months. At Lakeshore Pools, Banish is our best tool for preventing and eliminating all forms of algae in any pool including salt pools. Keep one step ahead and Banish algae forever!
