I'd go with a Cpr bak-pak, but skip the surface skimmer. I've not seen a version of the surface skimmer that works with a maxi-jet, and frankly that skimmer only works really well with a maxi-jet 1200 instead of the Rio 600 they used to sell em with.
Depending on where you get it, it may have the maxijet already...and that's how you want it. More reliable, more efficient, 100% easier to clean.
But, skimmers are noisy...mainly the HOBs...its a fact of life. You hit a pump impeller with air and water, its gonna make sound.
the bak-pak and the smaller remora's are not in-tank if you get the HOB
. the pump does sit inside the tank though, unlike the Prism, which is why they look a little different.
