FROG 90-Day Algae Barrier prevents yellow, green and black algae for 90 days – guaranteed with a 90-Day Algae Protection Guarantee.

1 pod provides 90-Days of Algae Protection for 10,000 gallons – Guaranteed

Using an algaecide is like an insurance policy. While you intend to maintain the right sanitizer level at all times, life happens and any number of things can deplete your chlorine levels and cause an algae outbreak. With a preventative like FROG 90-Day Algae Barrier in the pool, you are protected from that happening.

Using an algaecide frees up the chlorine to focus on killing bacteria, which lowers your overall chlorine usage and demand

Start with a clean filter and do not clean or backwash the filter for at least 2 weeks after using a pod.

If a pool gets algae within 90 days of using FROG 90-Day Algae Barrier, simply call 800-222-0169 and our Customer Service team will arrange a product replacement or a refund.

This is an additional step to maintaining a perfect pool.  It is a great product to use year-round, especially since most municipalities are adding more phosphates to the water systems to help maintain the aging pipe systems in US cities.  When you add a phosphate remover regimen to your pool care, in addition to a copper algaecide, you will make sure you are never having to deal with an algae outbreak.

Typically, in a few hours but no more than 24. The empty pod will float to the top of the skimmer, making it easy to remove and discard.

We have included a desiccant packet like those in medicine bottles to ensure the ingredients stay dry so they dissolve properly in the skimmer. When all of the pods are used, simply discard the empty package.
