PO4x4 Phosphate Remover (DISCONTINUED)

Product Name
No options of this product are available.

PO4x4 is a new uniquely engineered polymer mini pellet that is bound to a very pure form of FeOH2 (GFO) that will absorb phosphates in your aquarium without leaching any iron ions into your tank. The Iron based pellets can absorb up to 4 times the amount of phosphate than standard GFO. For best results it is highly recommended to use a fluidized reactor when using PO4x4. Canister filters can be used as well but will not be as efficient.

 

  • 500 ml will remove 3 ppm of phosphate and silicate from roughly 16.000 liters (4226 gallons) of fresh water or 8.000 liters (2113 gallons) of marine water.

 

Note: An ammonia kind of smell is normal when opening a new package. This isn’t ammonia but a processing smell during etching the iron on the polymer pellets. Overdosing can cause a negative effect in your tank due to rapid removal of phosphate and chemistry changes. It is recommended to use a small amount and gradually increase the amount of PO4x4 used, while monitoring the phosphate levels in your aquarium.

Product Questions

How much would you use in a 20g spa tank?
Question by: Abbas Jaffer on Oct 23, 2017, 7:48 PM
Hi Abbas,

According to the manufacturers directions 500ml of this product will remove 3 ppm of phosphate and silicate from roughly 8.000 liters (2113 gallons) of marine water. I calculated that you will want to use about 1 teaspoon of media in a 20 gallon tank but recommend starting out with half of that to see how your system responds.

What would be the comparison between this and BRS HC GFO?
Question by: Justin Wolpert on May 27, 2017, 10:45 PM
While we have not had the chance to do direct comparisons on the adsorption capacity between this and HC GFO, we have found this to be a very effective media solution, and due to the unique manufacturing of these pellets, they do have the advantage of being less likely to clump due to slow tumbling speeds, and will not grind up like normal gfo, so it makes for a very reliable and effective product.

Have a great day!
