The second 220 gallon I bought, this one near the entryway. It started leaking slowly shortly after I got it. I stripped all the silicone inside, resealed everything, and it began leaking again about a month later. It was a pain to move and set up because it was glass and extremely heavy, needing 4 people to move it even up and down off the stand for resealing. I did not want to risk it leaking again, so I sold it to build the seven tank rack instead.
