Hi Everyone! Just recently I decided to opt for getting a 60 gallon cube over the 45 gallon I was going to get. The sump that I ended up getting that would fit in my cabinet was the eshopps RS-75. The dimensions of the protein skimmer compartment is 7.5x9.5. I have only found 1 skimmer that would almost fit in that is the Skimz SM121 . I have no idea what skimmer to get. I just want the best possible that will fit in that compartment. Also, what return pump would I want for the 60 gallon? Thankyou!
