The ones used for Koi in the garden. Has anyone ever used them as reef tanks? I see people usin' Rubbermade horse troughs all the time, I would think that the ponds would be the same thing? They come in all differant shapes with selfs and what not, I would bet they would make a sweet look down/lagune/frag type system?
Just thinking out loud. If anyone has done this please post some pics.
