Supa Pond Anti-Algae Block

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.

Use one block per 1000 litres (220 gallons) of water. Replace when fully dissolved. Some plants may be susceptible from damage from use.
