Filter material for special filtration - the right one for every task

You can do much more with the filter than just reduce ammonium and nitrite. With the right filter material, your filter pot becomes an all-rounder in the aquarium, ensuring the right water quality. In addition to clear water, the reduction of phosphate and nitrate is also an important issue, especially in the prevention of algae plagues.

Algae plagues are dreaded in the aquarium. As a rule, the cause of excessive algae growth lies in a nutrient imbalance. The plants, which actually compete with the algae and limit the algae growth by their growth, are limited in their growth by a nutrient deficiency. The "remaining" nutrients, which they can no longer absorb for this reason, are then available to the algae.

As lower plants, algae have a few tricks up their sleeves as to how they can use such nutrient gaps to their advantage. For example, algae can obtain carbon from carbonate, while most higher plants rely on carbon dioxide dissolved in the aquarium water, of which there is often much less than carbonate. Thus, algae can access all nutrients, while their competition - the higher aquarium plants - are inhibited in growth. Especially an excess of macronutrients like phosphate (PO4) or nitrate (NO3) often results in an unsightly algae infestation.

There are effective additives from Dennerle for the filter: Dennerle NitratStop Supra absorbs nitrate from the water. This is a resin that can be regenerated when saturated with common salt and then absorbs nitrate again. This deprives the algae in your aquarium of an important nutrient. Dennerle PhosphatStop Supra is also effective against algae. It removes phosphate (PO4) from the aquarium water for up to six months, ensuring that it is not available to algae.

The Dennerle Clear Water Micro Filter Fleece removes the finest suspended particles and even helps with algae blooms (green water) thanks to the innovative high-density microfiber. Thus, the aquarium water is crystal clear and effectively cleaned of turbidity.
