iQuatics Bio-Phos 80 – Phosphate Remover
High-Capacity Phosphate Control for Marine & Reef Aquariums
iQuatics Bio-Phos 80 is a high-performance synthetic iron hydroxide filter media developed to remove excess phosphate (PO₄) from marine, reef and freshwater aquariums.
Elevated phosphate can interfere with coral calcification and contribute to nuisance algae growth. Bio-Phos 80 helps manage these levels by binding dissolved phosphate to its surface, allowing it to be removed when the exhausted media is replaced.
Key Features & Benefits
-
High phosphate adsorption capacity – Designed to remove substantial quantities of dissolved PO₄.
-
Synthetic iron hydroxide – Effective phosphate-binding filtration media.
-
Marine and freshwater compatible – Suitable for reef tanks and freshwater aquariums.
-
Helps control nuisance algae – Reduces excess phosphate availability.
-
Supports reef water quality – Helps maintain appropriate nutrient conditions for SPS, LPS and mixed reefs.
-
Versatile filtration – Suitable for appropriate media reactors and filter bags.
-
Wide operating pH range – Suitable for aquarium water between pH 5 and 10.
Phosphate Removal Capacity
iQuatics specifies an adsorption capacity of approximately 40–80g of phosphate per kilogram of media, depending on operating conditions.
The manufacturer's published performance guidance also states that 100g of Bio-Phos 80 can remove up to:
-
4ppm phosphate from 1,000 litres of saltwater
-
4ppm phosphate from 2,000 litres of freshwater
These are stated performance figures rather than guaranteed results. Actual capacity depends on water chemistry, phosphate concentration and filtration conditions.
How Does Bio-Phos 80 Work?
The iron hydroxide media attracts and binds dissolved phosphate as aquarium water passes through it.
Unlike liquid phosphate treatments, Bio-Phos 80 provides ongoing adsorption while the media retains available binding capacity.
Once exhausted, the media should be replaced.
Installation & Maintenance
-
Test your aquarium's phosphate level before use.
-
Measure the appropriate quantity according to the manufacturer's instructions.
-
Place the media in a suitable filter bag or compatible phosphate media reactor.
-
Ensure consistent water flow through the media without excessive agitation.
-
Monitor phosphate regularly using a reliable PO₄ test kit.
-
Replace the media when phosphate begins increasing or adsorption becomes ineffective.
Introduce phosphate-removing media gradually, particularly in established coral reef aquariums. Avoid reducing phosphate too rapidly or allowing it to become undetectable.
Why Choose iQuatics Bio-Phos 80?
An excellent choice for aquarists seeking high-capacity phosphate removal using conventional iron-based filtration media.
iQuatics Bio-Phos 80 – effective phosphate adsorption for cleaner, balanced aquarium water.
