Icecap skimmers any idea?

[WishNewFish]

Hi, I am looking for any general feedback and experience other members may have on using icecap skimmers?

I am looking at them for my redsea 170.

Any other suggestions? I saw bubble magus 5 but it may be overkill for the tank.

 

I saw icecap K1 50 and icecap k1 100 which may be near my tank capacity (40 gallons).

 

If you have any other better skimmers you had experience with in this capacity range or with goes well with redsea 170, let me know.

Cheers and happy holidays.
