Pond One Pond Algae Control Blocks 4 x 20g

Keep your pond crystal clear with Pond One Pond Algae Blocks, an easy and effective algae treatment available in a convenient 80g pack containing four 20g blocks. Suitable for use in freshwater ponds and tanks housing koi and goldfish, these blocks are perfect as a preventative measure, when algae first appears, or after cleaning an algae-infested pond.
Simply drop a block into your pond and let it dissolve over 7 to 14 days, depending on water conditions and circulation. Each 20g block treats up to 200 litres of water, while a complete block covers up to 800 litres, making dosing simple and straightforward. For best results, reduce sunlight or artificial light exposure where possible to slow algae regrowth, and remove heavy algae growth mechanically before treatment. Aerate the water after treatment to prevent oxygen depletion and repeat only when algae reappears. A simple, fuss-free solution for maintaining a healthy and beautiful pond all year round.
