Phospha-Guard Granular Ferric Hydroxide (GFH) Phosphate, Silicate & Heavy Metal Absorber

  • Rapidly and Effectively binds Phosphate, Silicate and Heavy-Metals
  • Massive Surface area for greater performance and larger Phosphate removing Capacity
  • Freshwater & Marine Use
Phospha-Guard Granulated Iron Media was specifically designed to absorb phosphate, silicate & heavy-metals from both freshwater & seawater. Once phosphates bond to its ferric hydroxide surface, it will not leach back into the system. This eliminates the inhibition of coral calcification and massively reduces prolific algae growth. Phospha-Guard GFH has a very large surface area (300m2/g) making it exceptionally powerful and giving explosive performance when compared to competing products. 1lts of Phospha-Guard GFH media removes more than 26ppm of phosphate / silicate or heavy-metals from 1 000lts of water! Phospha-Guard GFH can be regenerated 3 times over making it the most economical phosphate absorbing product. Phospha-Guard GFH is extremely effective in a fluidized reactor where slow abrasion slowly erodes the surface of the media, thereby continually exposing a new surface area to absorb phosphate.
What makes Phospha-Guard GFH superior to other similar products.  The amount of hydroxyls that are present in a media will directly affect the performance of the media. Simply put, there are more available sites for the Phosphate, Silicate and heavy metals to attach to and it will attach more aggressively. Other GFH products were designed for mains water treatment facilities. The pH standard in water treatment is pH 7.0 while the pH of Phospha-Guard GFH is between a pH of 8.3 to 8.5.

This not only insures that no pH drops occur in the marine aquarium, but, the media will also absorb Phosphates, Silicates and heavy metals more aggressively. Phospha-Guard GFH is made specifically for aquarium water and has been designed to specifically address the problems and challenges that aquarium water generally has. Phospha-Guard GFH can also be regenerated 3 times over with Phospha-Guard RE-CYCLE making the product far more economical than other products in its category

Directions for Use

Rinse with RO water before adding placing product into the tank to avoid discoloration of aquarium. Phospha-Guard GFH must be placed in a very high-flow area and is ideally used in a reactor, but, will also work in a MICRON ION-X 200-micron mesh bag that has been placed in a very high-flow area. If you are using a phosphate remover for the first time, you will use larger amounts initially. Use 0.5ml to 1ml per liter of aquarium water and once phosphate levels have reached below 0.10ppm, maintain with 0.25ml per liter of tank water. Some fines will be generated initially and will cause some cloudiness; this will not harm any animals and will clear in a few hours.

DO NOT LET PRODUCT DRY OUT as this will severely limit product performance, always keep Phospha-Guard GFH wet / moist. If Phospha-Guard GFH has been used in a media bag, massage bag gently every few days to rotate media and increase effectiveness. Always use a mechanical filter to keep organic wastes from covering the media as this will limit the products performance.

Available Sizes: 250ml / 500ml / 1lts
