Magic Filter is a water filter to ensure proper water quality and conductivity.
We reccoment to use ONLY distilled or demineralized water in ENBIOs. Why should we use Magic Filter then? Simply because it is a water filter filled with a resin to ensure proper PPM (less then 0.05ppm). It lasts for about 25 gallons of filtration. Changes color gradually from Blue/black to amber. When the whole filer has amber color, it is time to replace it. Hang vertically in place of water supply line.
