Yes - I'm THAT Mobile_gnome...
I bought those glass vase cylinders at a few stores (in the US) - Marshall's, Ross's, and TJ Maxx.
I had originally been looking for glassware at Michaels and HobbyLobby - and then my helpful Mrs pointed out that the housewares section of Ross's and Marshall's had lots of discount vases.
So I have been hitting all their stores in the area and have been able to pick up those nice glass cylinders in 4" - 10" diameter sizes for pretty low prices - the 6" dia by 6" tall ones cost $4.00 I think. (At one point I had actually bought all of cylinder vase inventory at the 4 locations in my town...)
Another good find was a 12" dia by 6" deep straight sided salad bowl that Old World Market was selling.
I have been going to the local glass cutter and having custom tops made. It's been like $3.00 a piece - which was very reasonable. They cut the round or the square and polish the edges for me. I have been fixing the tops on with paper bandage tape (breathes) or silicon weather stripping - but for the most part they're just held on by gravity.
My main use for these has been making Terrariums with locally collected moss specimens, but I have done a few nano-tank builds using 6" and 7" glass cubes and a TOM mfg'rd in-tank nano filter. Currently have Marimo balls in one and Dwarf Hair Grass in another. At that size tank - only White Cloud minnows, pygmy corys and shrimp fit comfortably - and I have been choosing to leave the livestock out of the equation.
I have been lighting the nano tanks with the IKEA LED lamps pictured in the shot linked in the previous message. I like those VERY much. Nice and bright and not too expensive.
