 | Depending on which type, chemical filter media control the pH-value and the water hardness (peat) – or reduce the phosphate level and inhibit the growth of algae (phosphateout).. The pH-value of mains water lies between 7,3 and 7,8 and is therefore slightly alkaline. However, most ornamental fish require acidic water – that is a pH-value under 7,0. EHEIM TORFpellets lower the pH-value and reduce the water hardness..
