Self leveling mat question

[fishyreef13]

I recently got a 38 gallon used tank. The self leveling mat got ruined when I was transporting it and I am looking to replace it. The dimensions are 24.5 by 24.5 inches. The self leveling mat I purchased is 48 by 24. So it is about a half inch or so off. Is it fine if I cut it and join the pieces in the center of the tank, so it will reach the end of the tank? or will this cause issues.
Thanks

Don’t see it being an issue.

You're worried about the "extra" half inch, right?

What kind of tank is this, BTW? (pic?)
