i prefer u get a better skimmer than seaclone. i have a seaclone, it doesnt do a lot job for my 55 gallon tank.specially u have a large tank. get ETTS or Marine Technical concept skimmer. i just bought the MTC, and the skimmer is doing great in my tank. if u are on the budget get the cpr back pack, i recomended very much if u are in the thight budget.
