Do you want pond margin plants / lillies but dont have a shelf? Or is your pond to deep for lillies to thrive on the bottom and need lifting up slightly ? Do you want and pond poum raised slightly off the bottom? These stands allow your fish to swim under and around them so no water volume is lost and they are completely fish safe, can be left in the pond all year maintenance free. I make these to order, they are available to buy, I post them next day to any UK address. Pleas
