Pond PhosGuard™ is a non-herbicidal, environmentally sound approach to the problem of phosphate control in ponds. It is a filter adsorbent that removes phosphates, silicates, and organic nutrients. A 2 Liter size treats over 600 US gallons.Pond PhosGuard™ is spherical. Its shape allows for maximum water flow through the media. Granular phosphate removers can become compacted, dramatically limiting their capacity to remove phosphate. If the media can’t come into contact with the water, it can’t remove phosphate from it. Pond PhosGuard™ is the only spherical phosphate remover on the market.
***Aluminum Oxide IS NOT REGENERABLE. No matter what anyone tells you, baking an aluminum oxide media does not restore its capacity to remove phosphate. This misconception comes from the product’s original intended use: industrial air drying. Obviously, if a product absorbs moisture, the best way to remove that moisture is to bake it out. However, that only removes the water, not the contaminants contained in that water.***
Directions: Use Pond PhosGuard™ in the chemical module of your pond filter. If a chemical module is lacking, place in your pond filter so as to maximize the amount of water passing through it. The beads are sufficiently large that a filter bag should not be required for most filters. Check the specifications for your filter. Each liter (approximately a quart) of Pond PhosGuard™ will treat about 100 to 300 gallons for 1 to 3 months, depending on the biological load of the pond. It works better at alkaline or neutral pH. Avoid using phosphate based buffers or fertilizers that contain phosphate or nitrate. Caution: May generate heat on initial contact with water. Pre-wet by slowly adding to a double volume of water (e.g. pre-wet 1 L of product with 2 L of water)
