Other than twice the price, would there be much of a difference between the Deltec MCE 600 and the AquaC Remora? I know everyone says that the skimmer is the one item that you do not want to skimp on in a reef tank but I am sure that there is a point of diminishing returns as far as cost over effectiveness. I really do not have room for a sump so an HOB skimmer will be the best for the 45 gallon tank that I have. I am willing to spend the money if there is really a difference.
