Which Skimmer?

[Craigdillman]

All I say is go bigger than you need

175 + sump, Curve 9 all the way if it fits.

How big is your sump? You will need to consider your space as a curve 9 has a big footprint.

It is a 20G, plenty of space in the skimmer section for the 9, problem is the depth, I believe the magus 9 needs 9.5-11 inches of depth, and my max is 9.

Your best option might be the curve 7

What about Cad lights Tia 1220?

Bit of conflicting info out there-places that sell it have these specs

Dimensions: 12.75" x 9" x 20"
GPH: 470GPH
Optimum Water level 7"-10"

Load recommendations:

Light bio-load (300G)
Medium bio-load (250G)
Heavy bio-load (200)

But cad lights website says this:

*Optimum water level 8"-12"
Load recommendations:
Light bio-load (250G)
Medium bio-load (180G)
Heavy bio-load (150G)

They run best at around 6-7" , and I agree with ray curve 9 is what I would do

[hillegom]

I believe the BM curve 7 is about 20 inches high. It requires a water level of 9.5-11 inches

[sgreen]

I run a curve 9 but find it runs best in 10.5 inches of water. That's why I thought a 7 might be better.

If you're going to have 200g of stocked tank, the 9 is the smallest I'd go, and get a new sump if you have to. The recommended sizes for all of these are a sales pitch IMO.
