Most disappointing equipment purchase

Worst had to be a Prizm skimmer at LFS pricing. This thing never skimmed, though I re-tried it at least 10 times.

My depressing story was my last tank. 400 gallons built on site. It was also cut apart and sold for cheap (lost about $3000 on that deal) after I finished sledge-hammering the marble tile wall i had it in. Only ever saw fw a few times to leak-test.

Good news was we were moving to a new house and I took that opportunity to build my current tank on the main floor.
