Sump vs. Aquaclear 70

[nestor29]

So the main reason I don't want a sump is because I would hate water overflow and getting all over the room. What you guys think about running a 40g with an AquaClear 70 and a HOB protein skimmer?? PWC every week.

That would be fine but your sump will not overflow if you do it correctly. You have to check the maximum water level your sump can hold. Do this by shutting off all the equipment, and the spot where when all equipment turns off and it almost overflows is you max. Where you're pump will run dry is your min. Find a place where you like the level the "most" and keep it there as best as possible. Letting it fluctuate in between max and min will result in big salinity swings.
