I just finished (or almost) the wet/dry filtration system on my 400 gallon tank. I have a Pondmaster 1200 gph pump for the return. My question is, I have 2 ball valves in line on the return lines(1 on each line)that are about 1/3-3/8 of the way closed. Will this put too much strain/pressure on the pump and harm it?
I plan on running a third overflow line sometime in the next week to help eliminate the issue.
