I'm not sure I'd want to move a plywood tank, although at the same time a 10x6 tank made of anything is going to be a pain to move. But with moving a plywood tank, you run the risk of micro cracks or larger cracks in the epoxy.
If you're not building in place, I wouldn't do plywood. Just my 2c
My ply tanks is built in one place then moved halfway through the country to my place in 4 walls and the bottom. Screwed it together and put in the pondliner and suddenly i got a bigger tank
