tank problem

[Griffin]

should be fine - i always fill any new tank to the top outside and let it sit for 3 or 4 days just to be on the safe side - slow leaks etc. It is close enough to the top and close to the structure side for strengh. Personally i don't see a problem but you could always try filling it outside if you have the room - just to be on the safe side.

cheers
