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.
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)
