Algae is another common issue in pools that aren’t properly maintained. Algae turns the water a yucky color, but it’s also unhealthy for swimming in. BioGuard offers products that not only kill any algae currently trying to grow in your pool, but also inhibits algae from developing in the first place. This is Step 3 in the proven BioGuard process.
Preventative Algicides

Back Up
For use in both chlorinated and brominated swimming pools, this algae preventative can work within those tiny cracks and crevices, where algae tends to like to start growing. Back Up stands as one of the most popular algae preventatives in the BioGuard lineup of products, featuring a powerful surfactant/wetting agent that becomes even more active as the water temperature rises — a prime time for algae to strike.

Optimizer Plus
Optimizer Plus works in conjunction with your BioGuard Pool Care System to suppress the growth of unsightly and unhealthy algae. Usable in all kinds of pools — chlorinated, brominated, and biguanide — you’ll want to use Optimizer Plus as much for the way it makes your water feel as for how it helps prevent algae. It makes water luxuriously soft and sparkling!
Algae Destroyers
Algae All 60
Algae All 60 is formulated to be used in both chlorinated and brominated pools. It works to inhibit the growth of stubborn algae with its foamless, non-staining formula.

If you notice algae in your pool, your first step should be to grab some Banish. Banish delivers results in as little as 24 hours. This patented formula is foamless and acts FAST to kill all types of algae. Formulated to prevent staining that can sometimes occur when using copper-based algaecides, Banish features a patented chelant for a high degree of effectiveness.
