The dissolvable blocks are unique in that they immediately sink to the bottom of the pond to more effectively remove undesirable bottom sludge. As the Blocks dissolve, they also supply a slow release of beneficial pond bacteria in the water to provide a number of benefits for Koi ponds and water garden ponds.
