Laffs....yup, it's amazing how good of a job macro is with absorbing nutrients. You don't realize it until you've cut back on your macro too much (been there).
Mine was leaking in the same place - even with the washer. I had to tighten the crap out of the inner nut to get it to quit - to the point of disfiguring the washer a bit...but it finally stopped. Been running leakless for months.
Ditto Hippo's comments. Tried removing the skimmer on my 10-gal for a month.....the algae bloom was uncontrollable, and I'm using RO/DI water. Had to attach it again for algae control. Oh, and I was doing weekly 10% water changes while skimmerless.
My advice would be.... If you want to try...
I've got a Maxi 400 (106 gph), and it's very quiet, although it tends to raise my tank temp about 2 degrees. Don't have any exp. w/wavemakers, so can't help you there.
Oh, and I'm new to this board, but not to reefing....
Good luck!
