Thats plan B (and probably what i'll end up doing). But I saw this: http://www.pondjournals.com/2011/09/pond-in-a-wooden-box/ -
Yeah or get a huge rubber maid container and pile cinderblocks around it, or wood and some plants to hide itDepending on the weather where you are you could always take a 40 gallon breeder (or other tank to your liking) and frame it all around with wood paneling or boards of some sort. It would be watertight and the wooden box around it would look nice.
I had one open bundle and a small pile of cut ends left over from having a floor redone. I have just enough long pieces to do the front. I'll have to use mostly scraps for the sides and the back will be open.Oak Hardwood floor? This will be nice enough to go in your house. :hihi:
Your "scrape" is way nicer than my scrape lumber. I built some Bonsai training boxes from old pallets.
