I think its already too late for that as the tank is already in service as a sump.If I remove all bracing now and the tank expands there will be no means to do this.Maybe the best step is removing the center bracing and hoping:biggrin: the end bracing will do the job.

That makes me nervous.............I hope that something tragic doesn't happen if & when you do take the center brace out.

I hope you are right.
Oh did I mention this is one of your tanks :biggrin: ...as I need to blame someone

:nono: wasn't mine, it was a buddies tank I just handled the transport :razz:

Just kidding:biggrin:
Well I am going to remove it now and will let you know the results as I will measure if there will be any expansion, hopefully it will take 10 minutes...
worse comes to worse and an exploded tank will have a flood of aprox 100 glns in my basement and will be calling you Greg for finding or bringing a replacement tank.

Well my fingers are crossed for you but if I do have to find you a new tank it might cost you a clam :twised:

A clam no problem as I still have 3 in my main tank:biggrin:
Having a little problem,How the hek do I remove it as its glued so dam tight that I cannot run a blade between the glass.

I use the smallest guitar string to cut sealed silicone.

Ahh I see,I will go and bug my kid for his guitar string:biggrin:

Use 2 wood dowels to hold the string or it will slice you up.
