Phospha-Guard Granulated Iron Media was specifically designed to absorb phosphate (Po4), silicate and heavy-metals from both freshwater and marine water. Once phosphates bond to its ferric hydroxide surface, it will not leach back into the system.

Benefits:

• Effectively removes large amounts of phosphate, silicate and heavy metals.
• Eliminates the inhibition of coral calcification.
• Accelerates growth in corals.
• Helps control unsightly algae.
• Reduces water changes.
• Freshwater and marine use.
• It can be regenerated 3 times over with Phospha-Guard RE-CYCLE.

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.
