Hi I currently have a Remora Aqua C skimmer that unfortunately for my tastes is too noisy and it heats the water because the pump has to be in the tank so I'm considering to use an external pump skimmer and I saw this two Reef Octopus Classic 90 HOB and the Classic 1000 HOB so I would like to know your opinion about those two skimmers, in resume I think one is a box (Classic 1000 HOB) and the other one is cylindrical (Classic 90) but any one can tell me how noisy they are, if possible in comparison with the Remora Aqua C and anything you can tell me about those skimmers will be appreciated.
