It didn't come from Planet aquariums but rather Deep Sea Aquatics. I misspoke on the Oceanic part but supposedly the people at DSA came from Oceanic. Good thing I never had a problem because they went out of business not long after while tank was still under warranty.Planet Aquariums (maybe that's the one in Dallas you are talking about?)
Glass Cages used to be not the best quality. But they are under new management as of a couple years ago, and people seem to be really happy with their tanks now.
I agree. Rimless tanks are inherently flawed. Personally anything over about a 2' cube, I wouldn't go that way.
There are rimless looking tanks that have eurobracing, like SCA, that I would be comfortable with.
Planet aquariums is a possibility I neglected. I have looked at glass cages in the past but always dismissed them for one reason. If I remember right, they didn't deliver and they expected you to meet them at whatever show they happened to be going to for pickup. I did look and that appears to have changed now.
