WHAT IS PHOS-OUT 4?

Phos-Out 4 is a specially developed polymer-based phosphate remover for ideal use in any marine or freshwater aquarium.

WHAT CAN PHOS-OUT 4 DO?

It quickly and permanently binds organic as well as inorganic phosphates in the aquarium.

WHAT ARE THE ADVANTAGES OF PHOS-OUT 4?

Phos-Out 4 allows a controlled reduction of phosphate levels without affecting the biology or health of the animals.

WHEN DO I NEED PHOS-OUT 4?

It is used to quickly lower even high phosphate levels.

Dosage incl. dosage calculator

Your aquarium (net volume of water in litres)		l
Freshwater aquarium: every 12-24 h	max. 4 ml per 100 L of water	ml
Saltwater aquarium: every 12-24 h	max. 2 ml per 100 L of water	ml

Dosage (freshwater aquarium):
Add max. 4 ml per 100 litres of water every 12-24 h, til the desired PO₄ value is reached.

Dosage (saltwater aquarium):
Add max. 2 ml per 100 litres of water every 12-24 h, til the desired PO₄ value is reached.

Important: Calculate the dosage based on the amount of water actually contained in the aquarium (without e.g. structures).

FAQ Questions and answers

Note that bacteria necessarily need a certain amount of phosphate as an energy source in order to carry out important biological processes (such as denitrification NO₃ nitrate –> N₂ nitrogen) in the aquarium.

Since NO₃PO₄ Control increases the growth and performance of the bacteria in the aquarium, the phosphate requirement naturally increases too.

Therefore, measure the phosphate value regularly (at least once a day) and add Basic P if necessary.

In order to lower the phosphate value (PO₄ value) in any saltwater or freshwater aquarium, there is the option of using Phos-Out 4 iron hydroxide granules or Phos-Out 4 liquid on a polymer basis. With Phos-Out 4 ganules you have a constant phosphate absorption over a longer period of time and with Phos-Out 4 liquid a fast, immediate reduction. Depending on the desired effect, you can choose between the two products.

Yes, phosphate (PO₄) is an essential energy source for bacteria in every saltwater aquarium and in every freshwater aquarium. If bacteria have no or too little phosphate (PO₄) available in the aquarium, they largely stop important biological processes such as nitrification (conversion of ammonium/ammonia into nitrite and then into nitrate) or denitrification (conversion of nitrate into nitrogen).

No, our Phos-Out 4 liquid is free of lanthanum and works on a polymer basis.

The ideal phosphate value in saltwater aquariums should be between 0.02 and 0.05 mg.
Be careful to prevent PO₄ shortage.
Use our Substrate Cleaner to remove phosphate deposits.
Dose in a strongflow area and not over your animals.

Phosphate deposits?

Use Phos-Out 4 together with Substrate Cleaner to break down otherwise inaccessible phosphate deposits and permanently remove them from the aquarium.
