Oceanic and Marineland use same bulkhead size?

[giants4pc]

Does anyone know if these two companies use the same bulkhead size holes in their overflows? I have always used All Glass. I now have the option of getting an Oceanic 156 gallon tank and was wondering if the same overflow kit for the All Glass aquariums would work? Anyone know for sure? Thanks,

Yes they are the same... 3/4" return, 1" drain. The Oceanic tanks typically come with the overflow kit included from my experience if purchased new.
