JBL PhosEx Ultra CristalProfi i60 / 80/100/200

The JBL PhosEx ultra ProCristal i60 / 80/100/200 is a ready-to-use phosphate remover complete set for use in the JBL ProCristal i filter for fresh and saltwater aquariums.

Besides calcium, phosphorus is the most important component of the bone structure of fish. But phosphorus also plays an important role in many metabolic processes, enzymes and other vital substances, as well as in muscle work. Fish have to meet their phosphorus requirements through food. Live and frozen feed naturally contains a balanced amount of phosphorus compounds.

Simple application
Nitrates and phosphates are the main algae nutrients. If one or both nutrients are removed from the water, algae can no longer grow.
No general statement can be made as to the time after which the binding capacity of JBL PhosEx ultra is exhausted since the amount of phosphorus in the aquarium is influenced by many factors: Young, still growing fish excrete less phosphorus than adult fish. High fish stocks cause more phosphorus compounds than less. In aquariums with dense, well-growing plants, more phosphorus compounds are consumed than in aquariums with poorly growing or without plants.

As a rule of thumb, the following can apply: In a 200-litre aquarium that is stocked with 1cm fish per litre of water and is not overfeed, one package (340g) of JBL PhosEx ultra remains active for approx. 5-6 months. However, this should be checked regularly with the JBL Phosphate Test Set PO4.

Application
The fully operational cartridge with filter tube can simply be inserted into the filter instead of the filter sponge. If necessary, this can be refilled. The plastic bag is removed and the PhosEx in the filter basket is washed out under running water to remove abrasion caused by transport. The cartridge should be replaced every 2-3 months or when the phosphate levels increase.
