like all of you I'm always keeping an eye out for affordable but spacious turtle homes (short of building a pond though)...and I've found these 3 links...sometimes the rubber/plastic containers are called poly tanks...I guess some of the tanks are way too big heavy for indoors and apartments (I got many warnings from turtle keepers) so be careful...frankly if I owned a home I would by a huge stock tank and turn it into an outdoor pond (no digging needed)
To calculate the weight of water in a container multiply the lxwxh divide by 231 then multiply by 8.5=water weight then the weight of the empty container
