I am new to this hobby and trying to build a 60 gallon reef tank. I am purchasing this sump second hand but it appears a different set up than most I have seen. The prior owner suggested bio balls in the right compartment. Refugium in the middle section. The return and skimmer section to the left. My though is to have a filter sock set up in the right compartment. Skimmer in the middle and return on the left. Possibly run a MarinePure block in the bubble trap. Is either option a better way to go or is there something else I should consider.
