Is anyone into aquaponics? I've seen some set up's at the Perth Royal Show ect and it looks great. The veggies look sensational and imagine having fresh trout or marron / yabbies for tea from the backyard...

If anyone has a set up could you let me know what it cost to set up? The pre made ones seem to start at $1000 and go up from there. Is it hard to maintain?
Finding the big (fish) tank without paying a fortune for it seems to be the key, as a water pump is only $100 at most. Looking on the net the only 1500L water tanks I could find cost heaps!!

Any ideas wouldbe most appriciated, and the seabreeze crew, whilst most definately nutty, seem a rather helpful bunch.
