Pond Block®

offers an easy, effective way to control and help prevent the growth of algae in your pond. It can help keep your pond clear from algae when used regularly.

Note: This is a slow release algicide and may interfere with the growth of floating and underwater plants.

Pond Block® comes in a package of four (4) 1 oz blocks.

Safe for fish.

Details: Replace when fully dissolved (usually after 30 days). For best results, place the block in an area of the pond that is calm. Not recommended for Water Lilies and Hyacinths.
