Algae Off is a water activated product made specifically for ponds, water gardens, koi ponds, fountains, and other water features with our without aquatic wildlife that kills algae on contact….Safely.
Crystal Clear Algae-Off, a granular algaecide for water gardens & koi ponds, works on contact meaning that it’s best used for Planktonic Algae (algae growing on things) typically found growing on:
- Pond liners
- Pond Waterfall Rocks
- Streambeds
- Fountain nozzles
- Pond Pumps
- Rocks in pond bottom
- Pond hoses
- ]Pond Spitters, fountains, etc
If algae is persistent, or frequent treatments are needed, be sure to:
Test the pH of the pond and adjust as necessary to proper levels, 6.0-7.5
Apply a barley bale to the pond when using Algae Off. Once the Barley Bale begins to break down, 2-3 weeks, algae treatments should be less frequent. It’s also recommended to test phosphate levels and use a phosphate binder if necessary. Phosphate is a major food source for algae. The regular use of beneficial bacteria, weekly – monthly depending on the pond, will also reduce nutrients available to algae making algae blooms less frequent.
