Hi Guys
Thank you so much for your thoughts
Here is the first stage of the pond
if you look at the larger shell you can see what looks like a black inlet or outlet ? not sure what it is but it is a hole which means I probably could work something out gravity fed or pump fed. with the water pumped into the deeper end travelling up through pea gravel and along that shallow part to the 'hole' and then feeding either into the big pond or the little pond. Or even using that outlet to draw the water out ?
or into the smallest pond an then into the big pond.
I would most likely use a piece of plastic tubing to achieve this ? and would just have to watch for it getting clogged and then using a pump from the big pond back up to the top again. My problem though would probably be clogging of the pipe ?
The other alternative is to not use the big pond at all and try to create something for frogs which would require less water......I would be pumping the water from the black hole through a shallow bog on the end of the pond and then through a mini bog in the small pond on the top. If I had a frog pond I would just use some australian native fish which eat mossies but not the froggies eggs. The size of the first two ponds is perfect for a frog pond and there is an advantage to encouraging frogs into the garden as with any luck they will eat the snails !!
I am sure I will work it out,,,,and the ponds are very cheap on ebay rather than buying new so I will have some spare cash to get a good pump
Thanks for letting me know about synchronising the pumps I hadnt throught of that I am probably better off using one larger pump with plenty of capacity and thinking about how I might set it up to do the whole lot.
You've all really helped me heaps !
I promise I will post piccies when it is finished and will lt you know what I have decided to do.
Kind Regards
Elizabeth
PS where I am in Australia if we ever had snow I would be VERY excited lol
