I run a stock tank sump Jeremy. It’s 100 gallon and full of live rock. It’s difficukt to use filter socks but not impossible. I run an external skimmer so that’s not an issue but when I ran an internal it was an issue. If I was able to I would have used starboard or pvc board to create some dividers for ease of using socks, skimmer and anything else it might make more convenient to use. The idea to use both is a great one if you have the room. Best of both worlds.
