working on my aquaponics system as well.. just ordered 3 yards of gravel for my growbeds.. it's going to be less than fun hauling it all into the basement, but i gotta get it done
That should put you in shape for your summer speedo while showing off at the pond! :cry
I unfilled mine by shoveling the gravel into my front end loader. Even that was a lot of work. I'm thinking it was less than a thousand pounds, and maybe a quarter of a yard. It was a lot easier filling it with the loader. Cleaning it was the hardest.
