Specs say 1600GPH, with gravity feed.

not sure i understand what you said at all lol im a newbie with plumbing and this is my first tank with a sump, it was all pre-plumbed, drilled etc. im just trying to make it less noisy.

generally people use bulkheads that look like this:


What you can do is use this male adapter:


and make a nut for it by cutting a female adapter off at the threads:


You will need a seal still, so using the seal from a bulkhead, or finding one in a hardware store works fine.


The only reason to do this is to get a little bit extra flow through a smaller hole. With a bulkhead you are inserting a bulkhead into the hole, then a pipe into the bulkhead, this reduces the hole size that water actually flows through.
