Description

When placed into the pond this block slowly dissolves releasing di-methyl urea into the pond waters. Whilst totally harmless to fish and healthy pond plants this inhibits the growth of water born algae. Prevention is always better than cure so the introduction of this item in early Spring will prevent build up of algae as the weather warms. Directions Place the Supa Anti Algae Pond Block into the pond during early Spring to prevent algae growth as the weather warms. Box Contains 1 x Algae Block
