Protein skimmer - what type

[ninjamini]

I have a Protein skimmer that sits in sump. I was thinking of trading it for a hang on. Is there any differences either way in terms of quality?

Here is the one I have:

Hang-on skimmers by nature tend to have small reaction chambers, which can limit their effectiveness. My general advice is to go with the largest model that fits your sump and budget.

If I put the skimmer into the sump it greatly reduces the amount of room I have for cheto. Can I pipe a in sump skimmer outside the sump and still have it be effective?

Sure, just make sure it doesn't leak.

Some in-sump skimmers are not designed to be leak proof and therefore can only be used in-sump. All "external" skimmers can be used in-sump so long you have the space. Make sure your skimmer can be put outside, withotu any leaking, like Jeff says. Also, make sure the dischrge from the skimmer is higher than the sump's vertical wall otherwise the level inside the skimmer chamber will run to high and make it flood onto your floor.
