I got a 10 gal tank from my grandmother today an this thing is old. The last 10 gal that i had was made with 1/8th" glass, this thing has 3/16th" glass. Ive never seen a tank yet that has a frame that not one piece, plus theres no lip on the top frame for a hood or canopy to sit in. I took some time an resiliconed the upright seams just to be safe as the bottom seams look pretty good.
