I have a 550 Gallon Reef / Fish tank. The tank does qualify as a heavy Bio load tank. I would like an in-sump skimmer. Im not looking to waste money but I want to buy what Is considered the best for my application. Was thinking the Regal 300 SSS Space saving skimmer (500-700Gallons) -Reef Octopus. Royal Exclusive? is it worth the money and that much better than the Reef Octopus? Please let me know your thoughts.
