Hi everyone, I am new to saltwater and I purchased an Octo Lux T-90 48 gal ATO tank with an Octo 30B Sump, Octo INT-150 Protein skimmer and return pump. My question is, from my picture...am I set up correctly? My heater is in the chamber of the skimmer. The adjustable wall on the left side of the sump is down. Does it need adjusting?? Where would I put any bio stones etc? What about macroalgae? Where would it go?
