For what it’s worth, BRS sells a kit you drop into standard glass tanks to make them AIO. I think it’s a cool concept but have no use to do one myself just was looking into them out of curiosity recently. Worth looking into considering you can grab a new tank for $1 gallon
I have one of those fluval edge tanks 13.5 gal AIO comes w everything light hood pump etc, if you need a stand I can offer a stand as well if that’s something you may be interested in I don’t have space for it I even have the skimmer for it I’ll toss you.
