hi ozy,
small setup??? how small is small, care to share the tank vol?
IME, i hv used the red sea prizm and AquaC Remora b4. hv not used the Deltc H.O.T skimmer b4 so shall nor comment on that.
IMHO, prizm was doing fine till i started venture deeper into corals. the capacity of the skimmer is overrated. AquaC looks good and work fine. in fact, i wld say it is better in terms of performance as compared to the prizm. u can ask hippo, he bought my Remora.
there some other hang ons in the market, i believe the macro needlewheel can oso be hang on and the reviews on it so far are quite positive. but of coz, it wun be as slick looking as the meant to be H.O.T skimmers like deltec or remora.
juz me 2 cents.
