yeah man the tank was off level, thats also why I only filled it half way or less. will be empty in a few hours and re leveled. I think the back leg I added (the circle poles) I pushed the tank up too much as I whacked it with a mallet.
I must say it does look very nice, hopefully it will hold water when full!
Sorry missed the fiberglass Q, those ones are 15k, the glass is almost half of that alone. My tank builder does build tanks all of aus on call outs but I am not sure about the costs, I can pm you his details if your keen.
