I have a question I have a 55gal reef and would like to change the overhang skimmer with a reef devil that I just purchased. I am looking to put the reef devil in my sump but my sump is too small so I decided to try to configure my 10gal. that is just laying around for my purpose and wanted to know where I should place the dividers in the sump? Also since the skimmer will be put into the sump would I still need to use Bio balls? Thanks
