Ok here is background info you need to know.
I have two 40 gallon tanks (stacked)
Running off of a Mag 9.5 in the sump
The plumbing running to and from the two 40's is 1"
The tanks are drilled with 1" bulkheads
Would it be wise even though it has a 1" bulkhead, to plumb the drainage in 1.25" or bigger?
