Tank not sitting flush in middle

[islanddave]

Hello All
I hope that it is ok to post here if not mods remove or move.

I finally got my stand built and it is well made and straight. 3/"4 plywood top and 2x6 inner construction.

I placed the tank on the stand, and although all four corners of the tank touch the top of the stand the bottom trim of the tank both front and back do not. This starts at the middle and goes to about 6" from each corner. The sides do not do this.

250 gallons 60"L x 36"W x 27"H

Should I be concerned?
Hard to capture in a picture removed weirs going with a hob life reef and using an old ehiem for a closed loop

FYI .085" clearance max at middle

Thanks David

Dude that makes me feel a bit better.

If the tank has a plastic trim this shouldnt be a problem

 

[islanddave]

Plastic trim it does have

 

[millerkid519]

Yes it does but a gap make the trim useless. It's all in the strength of the glass. This is a 20 year old tank that is 5/8 glass and only resealed once

Sounds like roughly the thickness of a nickel... got a couple to spare?

I had the same issue when I built a stand for my 210. I could never build up the nerve to fill it up.

Would something like this work?

If i were you I would drain it and put a piece of 1" insulation Styrofoam between the tank and the stand. I have seen a few massive tanks blow out because of something like this. there is odd stresses being put on an uneven tank and over time with sealant becoming weaker it will go bad. that pad is like $20 and will give you peace of mind.
