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 detoxificate 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®.
