djay Posted May 23, 2010 Report Share Posted May 23, 2010 Help can someone tell me what the best thing would be to hold polythene air tight so the water runs down the outside of the polythene having a problem it seems to quietly seep out down the inside and not through to the pond could i just use water proof selant I cut the hard plastic container length out the i want water to go down the falls. but can't seem to get it water tight so it all goes back into the pond. Does anyone know what i could use thanks. the ponds alright it has 1800lph with fountain, I'm going to bring the height down of the fall as well .so it has more pressure. so the hose coming out from the pump is running into the filter box aat the top. Any body any ideas. Thanks Quote Link to comment Share on other sites More sharing options...
Caryl Posted May 23, 2010 Report Share Posted May 23, 2010 I found it a bit hard to understand the problem but you should be able to use silicone I think. Quote Link to comment Share on other sites More sharing options...
