When I had freshwater tanks, it was my dream to have a sump
Now that I have a SW tank, I am SO happy that I have a sump, with ALL of my equipment in it
The best part for me is my sump is in another room, so I don't have to listen to it
Whether or not you can place a sump in another room, or under your tank, a sump is a great addition to any tank system
You'll add water volume to your system by doing so, so just do it !!!
You won't regret it
