Serenity Pond Algae Blocks are green water destoyer blocks perfect for controlling most types of algae in fish ponds and freshwater aquariums. Pond blocks kill algae and also prevent it from growing again. A substance in the pond algae block attaches itself to any floating dead algae which causes it to sink to the bottom of the pond. The dead algae can then be siphoned out of the pond or left to break down by natural bacteria. It is best to use pond blocks with a running pump for better water circulation. Treats up to 800L of water (or break into 4 small blocks to treat 200L at a time.)

  • Crystal clear pond water
  • Frog and turtle friendly
  • Kills algae and prevents it from growing again
  • Works for up to 2 months
