Remora Pro vs. Coralife Superskimmer 220

[Mekong]

I have both, which one should I use as only one fits in the sump.

The remora of couse will have to be modified for sump use of course but that should be easy, and I have a mag 5 or 7 to use on it.

The CSS is already under the tank and is working fine, but I wonder which will work better.

Try them both and see which works better. I never had a CSS, but the posts I've seen show they work well. I did have Remora Pro and was thoroughly unimpressed.
