Thanks TeeGee......that is actualy ,VERY good thinking ! :D I had better move it into a safe place. It is rare for us to get frost here ....but it is still possible...and I think its set to turn cold again next week ? ::) I ve been looking at some library books about making small water features and ponds.....it seems it can all get very expensive :o . Well ,I,m thinking of recycling some plastic sheeting I found at a local nursery (it was in a free to take bin ) and I have quite alot of it ...I,m also going to make a tomato growing mini-house thing with some of it (O.K so I grew up watching Blue Peter :D ) I will use sand and an old blanket underneath the several layers of quite thick plastic . Rocks around the edge to hold all in place and arranged to look attractive and my waterlilies in the middle . The thing I need to know is this ---- To save me buying a pump ,can I use a simple and CHEAP oxygenating plant instead ? There will be no fish ,this is just for the beauty of reflections and Dragonflies . Thanks again Rohaise
