The only filtration you need is the LR
and the DSB
. You can add a skimmer if you want one. If you don't use a skimmer, you will need to feed sparingly and stock lightly. A wet/dry works fine for a fish only tank, but it will cause your nitrates to be high in a reef...actually it causes the same problem in the FO
, but you control it with water changes. Nitrates are more of a problem in a reef as many inverts are sensitive to them. You'd be better off to just have the sump and place your heater, skimmer, ect... in there.
You could use the canister, without media, for circulation. You could use it to run some activated carbon occasionally. If you run it with media, it will cause the same problem as the wet/dry.
lighting is fine...it's what I use mostly. I don't know how much you have on the 30, but I doubt it will be enough for the 58. It really depends on what you intend to keep. I'm thinking a 58 is 36" long and about 20" deep? I'm no lighting expert, but here's my guess for the ultimate system. 2 175w (250?) MH
and two 96w PC
actinics. It has been said that VHO
actinic is more intense than PC
...I really don't know. If you're gonna stick with PC
, I'd say 2-96w would be minimum.
