.... my tank just cracked....
I stuck some holdfast on it and it seems to be doing the job for now... But it still worries me... I'll probably get a new tank tomorrow...
All better.
I located a drill and drove the 30 minutes to work and got a new tank and had it drilled. We didn't have the right fittings for a 1" bulkhead and couldn't find the drillbit for the 3/4". But i figured it out with a 1"
it's cleared up and looking good!
