Hey guys! I bought a 39 gallon hexagon Oceanic aquarium from OfferUp. I can't remember if the bottom glass plate is tempered? Does anyone know if they are tempered on the bottom plate? I plan on making this Hex a freshwater low light planted tank without C02. This will be my first so if you have advise on plants , fish, substrate and lighting that would be grate. I will also be doing my own research. Thanks for the help.
