watch the tanks though. seals are very sloppy and bad, glass overlaps in the corners and is very rough/sharp, I could see the edges cutting fingers open very easy.
Yes PETCO'S $1 gallon sale on Aqueon Tanks are "seconds". I contacted Aqueon about two tanks I purchased from PETCO leaking around the top frame. They explained to me that PETCO has a contract with them to purchase their "seconds". This also maybe the case with other products they sale other than tanks too!
