Green water and blanket weed are a nightmare for pond keepers and can be a pain to get rid of. The Algae Block is a mild treatment that gets rid of algae without harming fish or plants.
The tablets come with a free dispenser which floats to help the Algae Block remain on the surface where it is most effective. We also have a refill pack of 2 Algae Blocks available; just choose what you need from the drop-down menu.
