*by J***T on 2 September 2014*

The product arrived labelled sludge remover but as we had had so much trouble even finding Pond zyme plus in Britain we decided to give it a go anyway. It has certainly made made a difference to the pond weed accumulating but I wish I knew whether this is the same stuff we used previously ie pond zyme plus.
