Blue Planet Pond Algae Control Blocks 4x15g

Blue Planet Pond Algae Control Blocks (4 x 15 g) effectively control most algae common to freshwater fish ponds. The blocks kill growing algae and help prevent algae from recurring, restoring and maintaining pond water clarity.

Features

• Kills existing algae and helps prevent new algae growth
• Blocks gradually dissolve over 7-14 days depending on water conditions and circulation
• Active constituent: 13.75 g/kg diuron
• Pack of 4 x 15 g blocks
• Made in Australia

Directions for Use

• Add one block per 200 L of water (1 block for ponds of 100-200 L, 2 blocks for 210-400 L, 3 blocks for 410-600 L and so on).
• Best used as a preventative, when algae first appears, or after cleaning an algae-infested pond.
• Distribute blocks evenly to cover all areas of the pond.
• If possible, control the amount of sunlight or artificial light to reduce algae growth.
• Repeat only when algae reappears.
• To prevent oxygen depletion, remove heavy algae growth mechanically before treatment and aerate the water after use.

To calculate approximate pond capacity: length (cm) x width (cm) x depth (cm), divided by 1000 for litres.
