removing weld-on acrylic glue

[the big kahuna]

I believe the previous owner of my 240 8×2×2 accidentally spilled a little weld-on on the outside of the tank about the size of a silver dollar coin. What's the easiest way to remove this. Again is definitely on the outside of the tank. Thanks in advance for any advice

Your going to have to sand it down and polish it out

Weld-on is not a glue. It's a bonding agent that acts as an emollient to literally melt acrylic to molecularly bond multiple acrylic surfaces into a single piece of acrylic. Once cured, there is no 'glue' residue. All that's left is the bonded area.
Your only recourse is to treat the weld mark as a scuff or scratch and buff/polish the blemish out. There are multiple DIY articles on polishing acrylics.
