I am HOB skimmer shopping. Its between the Aqua C Remora Pro, the Deltec mce300 and the Deltec mce600. I have seen a lot of negatives about the MCE 300 and we all know the price of the MCE600. I have heard pretty good things about the Aqua C. Is the MCE600 really worth the money? Also whats the latest on the MCE300?
