I bought that metal stand on the right for about $40 from Target last year to be a speaker mount, but its dimensions are perfect for the sump area. I'll use it to start, until I learn what's the best way to deal with power strips/plugs/etc.Been so afraid the tank was going to crash through the floor, but finally made some progress tonight.
Also, added an $8 battery powered motion sensored led light strip to the upper left of the cabinet. Saw another thread that used Torchlights LEDs and ordered them, but while they work well, they are way too powerful for the small sump place, so I'm returning them to reduce clutter. One less thing to plug in.
