Clean and healthy water
Plant and food remains and metabolic substances lead to a deterioration of the quality of the water in the aquarium. Good water quality is necessary for healthy fish and plants. This can be achieved with various filters and filter materials. The filters suck in the aquarium water and remove the pollution and waste materials from the water.

Easy to use
Cut foam about 1-2 mm larger than the relevant cross section of the filter and put it into the last filter stage. Avoid gaps between the inner wall and filter. Coarse foam as long-term filter material.

Fine filtering
The fine material filters even the smallest particles (1/1000 mm upwards) out of the water. This removes floating algae and very fine turbidity from the water almost immediately.

Absolutely safe
No release of pollutants into the water from neutral foam. Open-pored through dedicated high-pressure treatment.

Frequently Asked Questions (FAQ)

_x000D_

I have green water in my aquarium, and even water changes and changing the filter media only helps for a short time.

_x000D_

_x000D_

Green water means floating algae, which grow when they have no competition from other plants and, even more, when the excrement of the fish creates excessive nutrient pollution in the water. The filter will not be able to do much about this. Ultimately, there are only two possibilities:


1. Carry out significantly more water changes in order to remove the nutrients caused by fish excrement.


2. A JBL AquaCristal UVC clarifier kills off the floating algae.


A temporary measure is to switch off the light for 2-3 days in order to stop photosynthesis in the algae.
