I'm looking into getting a 23 gallon tank from glass cages and before I pull the trigger on anything I want to see what I should do as far as pumps and protein skimmers and what not. I always hear great things about Eheim pumps and was wondering what everyone's impression of the Eheim 1048 was. Too much or not enough pump for a 23?

Oh and btw the dimensions are 18x18x16 rimless
