no one builds acrylic tanks in brissy. just get a glass one.
I got a huge peice of wood for my new pond. about 10' in length and weighs at least 100 kg. ive got a mate whos an arborist, so as not to f up the new pond we're gonna pulley it in to get it higher then 4'. LOL gonna be mad. its like a long hollow trunk with an end that fans out . we had to carry the darn thing out of the creek, hard work.
