Answer:

If your tank is predrilled use the largest type of bulkhead that will fit. If your tank is not drilled, determine the necessary water flow (remember to consider the head distance!) and pump. That will tell you from the outlet the size you need for return and drains. Get slip if you like PVC piping, I use threaded for vinyl hose as I want quiet and the vinyl absorbs vibration from the pump.

If using a bulkhead with a rubber gasket, is it still necessary or recommeded to seal with silicon? If so, which type?

I have a reef ready tank and have the eshopps bulkheads with the rubber gasket. Should I also use silicon to seal or is the gasket designed to perform that function?

Answer:

The gasket will do that. I have not sealed and had no problems after 8 years (3 bulkheads of 1.5, 1.75, 1.75). Setup and run your tank with fresh water for a few days to check it out. Be careful not to overtighten the nut below (they crack) and consider using a fabric washer between glass and nut on the outside of the tank (tip from my handyman) as it prevents glass chafing. I noticed some slivers after doing teardown on that 8 yo tank on one hole.
