OMG im so MADDDDDDDDDDD! I just wrote out this post.. took me about half hour... and AOL decided to disconnect JUST BEFORE I clicked Add Reply.
anyway.. i spose i better start over.. calmly..
We have marked out the pond with string, pics..


See the yellow string next to the stepping stones.. Pond!!!
So its question time..
Its about 12ft long and 3ft wide at the widest bit, hopefully be about 1m deep, how many gallons would you guess (or work it out) to be? Also take into account there will be shallow bits round the edge for plants etc. and one end will be shallow, so fry have a place to hide from big fish!
Dad is moaning about all the money its costing him, so the filter is going to have to be a little DIY job, im thinking a tub, some tubing and a pump?
It will have to be dug into the ground in the middle of a flowerbed on the right side of the pond. Mum also wants a bog bit so she can have bog plants

and newts like it too.
Will my DIY filteration be enough?
If anyone has any suggestions.. talk away!! we need inspiration!
