well put, i prefer a dsb to cc and ugf's, had both, hadd a mix, and now only have dsb
don't mean to be too forward but i particularly dont care for wet dry's either, IMO i would prefer to have a dsb and skimmer for most systems,
now don't get me wrong teh other methods do and can work, but as mentioned adsb is easier to switch out now and much more preferred amoungst most of us besides the switch now would also be a big benifit if you decide later it is a major PIA in comparison to switch later after you have adopted fishes
as for options, what options are you looking for, fish reccomendations?
if so, keep in mind that in a 30 galllon you are limited, i would only get 2 or 3 smaller fish that will stay small, like a pair of clowns or damsels or firefish or something like that and a lawnmower blenny to help with algae and personality
beyond that welcome to a great addiction
