Can you OVER-skim?

[andresont]

I would buy the biggest skimmer your set up can take. For me also a quietness and power consaption is a big factor. I like Tunze skimmers 230 and bigger one 240 very nice and quiet, the only drawback is you need a sump with constant water level.
I have never seen, talked or herd of anybody who would say : "yea i need a smoller skimmer"

Look under the display cabinet of you LFS and see what they have there...
J&L has skimmer rated 10 times their tank volume.
