[qwikcustoms]

This is in regards to the Marineland 45 gal Cube 924x24) I love the tank size but not the way they located the bulkheads on the rear panel . Does anyone know if the bottom is tempered , Thanks in Advance,paul

from what I remember they are tempered. Even where the bulkhead is drilled. I believe they drill then temper afterwords. I could be wrong but I'm pretty sure that's how they do it. If all else fails call marineland and ask them directly.
