In the land of rec.aquaria.marine.reefs, the word of the Lord came
to Marc Levenson and verily he spoke saying:
Each model of the Euroreef line will have MFG's recommended depths
listed for the model in question. You want a skimmer that matches
your total water volume, plus some.
If you have a 75g display, plus a sump, I'd look for a skimmer
that can skim 150g. Remember, I have an Aqua C Ev-200, rated for
200g on my 55g tank.

Thanks marc,
I guess I already knew that I was just hoping that the CS6-1 would
work. I don't know if the CS8-1 has too large a footprint but I
definately need a 20" tall one for it to work. Where is the best price
available on these models.
