Seachem Pond PhosGuard 2L (67.6 oz)
Seachem Pond PhosGuard is a filtration product that promotes algae control for ponds. It is a porous adsorbent that removes phosphates, silicates, and other nutrients that support algae growth. It does not harm aquatic plants. It does not release anything into the water, but instead works by starving algae rather than poisoning it.
A 2 Liter size treats over 600 gallons.
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).
Caution! May generate heat on initial contact with water. Pre-wet by adding to a double volume of freshwater (e.g. 250 mL of product in 500 mL water), followed by a rinse.
