Use of Puritabs (chlorine tablets)

The water in the tank must be cared for regularly, because over time, residues and algae build up. These are eliminated with the Puritabs. The chlorine tablet is placed in the water through the tank opening and dissolves in it. Do not use any other chlorine-containing products or chlorine tablets! Do not use the blue water color at the same time as the chlorine tablet. The chlorine tablet dissolves the blue color!
