i would get the bulks first then get a bit bigger then the bulk.

You can pick up tank drilling sets on Ebay for glass tanks. They cover all of the common bulkhead and flange sizes.

when looking at bulk heads i noticed that some say what size hole they require i need to know how close to that size i have to get like how much bigger can i go?

this is a guess but i would think each bulk could be different sizes.
thats why i say getum first then measure.

size of bulkheads can be off by .25 in. between manufacturers (patent infringement etc.).

If you know the manufacturer or the distributor contact them for best results (and you can blame them if it's wrong )
