sorry missed this..
Nyos 120 would be small, if you want that skimmer go bigger.
RLSS R6i would be perfect but it is hard to get now and I am not recommending the new ones because I have not tried them. I am guessing they are pretty good but even those are hard to get at the moment.
ATB 840 V2 is great skimmer for that size aquarium.
I also like the Deltec skimmers nice work horses and can be bought from Battle corals just ask Adam on the sizing. I would look towards the ones with Aquabee pumps.
I would like to try the new cone skimmers myself, I hear great things about them.
