PREIS KOHLE® is small and cylinder- shaped and free of all toxic residues. Active substances and useless debris are separated during a special process, thus yielding a product with a 100% active surface. PREIS KOHLE® can be used safely by all aquarium owners due to its absolutely neutral pH value.
The use of PREIS KOHLE® should be however suspended when applying therapeutics and reintroduced only after treatment in order to detoxicate the the water.The following analytical data show the unmatched efficiency of PREIS KOHLE®:
1. 10 g of PREIS KOHLE® adsorb 7 g of organic acid and its salts
(test substance: sodium acetate).
2. 10 g of PREIS KOHLE® adsorb 8 g of dye (test substance: methylene blue).
3. 10 g of PREIS KOHLE® adsorb 5.8 g of protein (test substance: egg albumen).
4. 10 g of PREIS KOHLE® were autoclaved at 180° C for 2 hours in
1l of bidistilled water and subsequently aspirated through a membrane filter. The water was evaporated and the residues heated to 900° C in a platinum crucible. The process yielded a residue of 0,01 mg per 10 g of PREIS KOHLE®.
The first recorded raising of the shrimp species “Palaemon elegans” in our facil- ities in February 1976 provides evidence that PREIS KOHLE® is indispensable for the setting up of an artificial ecological system.
This successful experiment shows also that phytoplankton (one-celled plants) and zooplankton (animal plankton), which are necessary for the raising of shrimp larvae, thrive in water filtered with PREIS KOHLE®.
