I'm trying to reuse as much of my existing equipment from my 20 in my new 40 build. I will use the 20 as the sump,and was wondering if there is any reason not to use the HOB
skimmer I have. It's sized for a 75 (eshopps psk 75) so it would have plenty of capacity given the displacement of the sand and rock, and the sump won't be completely filled.
The only issue I foresee is the intake and output tubes may not be long enough...
