I'm putting in 4" bulkheads into my 150 gallon rubbermaid stock tanks
and was wondering if anyone uses silicon to seal the bulkheads or to
just leave them as is (plain rubber). Once I put these tanks in
place, it would be a real pain to fix a leak, so I want to check what
everyone else has done. Has anyone put in bulkheads into a rubbermaid
stock tank? If so, what have you done and did they ever leak? Thx!!!

I didn't seal mine, just used the rubber that came with them. I am on my
second filter with the same bulkhead fitting and no leaks. I thought about
using the silicon.
But if you would feel more at ease use the silicon.
