Im struggeling with chosing a skimmer with all the options out there. I would like my tank (180 gallon) to be a heavily stocked mixed reef in the end. All within the same prices. A new Coral Box D700+, used Reef Octopus 202s or a oprn box Bubble Magnus Curve 9. Ive hear good of them all. One thing that scares me about the BM is people reporting it being very loud. What do you guys think, im trying to stay around 400 Canadian $.
