Hi all
I noticed a few of you are getting cracked tanks. Reason , stress.
Cure : use 2 or 3 - 1 inch strips of glass as a brace/ and silicone them from the top front endge of the tank to the back.
it is best to reduce the water level by a third and let the silicone go off and then raise the water level back.
the new strips will prevent any bowing causing stress fractures;
This is the biggest failure in people building there own tanks

hope this helps.
