• The balls are designed to fit into a filter but if in certain instances it will not fit, simply break it into pieces and insert into the filter.
  • Do not place The Water Cleanser directly under a hot light as the wax could melt and leave an oily residue in the tank.  This is not harmful and will disappear within a couple of days.
  • For best results, ensure that the tank or aquarium is partly shaded as this will prevent excessive growth of algae.
  • The Water Cleanser works best when placed where the water flow is greatest.  Use a weight with some string to anchor the block in place.
  • The date can be scratched onto the block to serve as a reminder for the when it should be replaced.
  • Rinse the product under running water prior to use to remove any potential contaminants.
  • Use more than one block or ball in the water system to allow each type of microbe to be established without clashing with the other beneficial microbes or bacteria.
  • The Water Cleanser works even better when plants are in the aquarium or pond.
