Which Skimmer?
 

I will be setting up a 175g bowfront reef in the near future and I'm considering one of these 4 skimmers.

Any pros and cons of each, which would be better?

1:TUNZE DOC Skimmer 9410
2:Bubble Magus Curve 7 Protein Skimmer
3:Bubble Magus Curve 9 Protein Skimmer
4:CAD Lights TIA-1220 Conic Protein Skimmer

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

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

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)

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

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.

Plus it's not much more money then the 7 and then you open yourself up to adding more volume if you ever need it like a frag tank or external Refuge etc.

Yupp if you're going stocked you need to double the rating with most skimmers available to the masses.

You are going with a 20g sump on a 175? You may want to rethink that unless space is an issue. make sure you have enough room for a power outrage, 20g is a tad small for a 175.

Have you calculated if your 20g can hold the back flow of water when the return pump shuts down? A larger sump is cheap insurance and won't limit your equipment choices. Will also give you room to upgrade down the road for adding reactors or other such things.

I busy eating and see Ray has the same concern!

Didn't have much choice for the sump-kinda came with the tank lol.

I haven't set anything up yet-still in the planning phase.

If you have room, I'd upgrade that a bit. Depending on your setup, a power outage could easily flood that sump.

I've been keeping my eyes open for a 40g/50g tank I can modify into a sump with fuge.

Anyone heard of the new Coralbox DC Curve Protein Skimmers?

Runs with controllable jebao pumps.
