Dear fellow reefers,please pardon me for bringing up this topic again.I am really in a dilemma to make a decision on whether to get a weipro skimmer or a macro needle-wheel.Fristly,my budget is $100 or a little off $100 or jus below 100.A weipro and a pump may cost as much as a macro,but which skims better?Wat i want is a skimmer that hangs like a hang-on filter.BTW,i do not hve a sump so i do not have a place for skimmers that are too big.Please give honest opinions!
