I am receiving this tank this Friday. Would like some input on what type of sump setup would be best for keeping sps coral and tangs with coral beauty. The setup will be different as far as the aqua scape goes the picture is from the person I bought it from. I was looking at the Triton method design. And I also need help as I don’t fully understand about dosers and as to if I am going to need one or not. I am going to set up an rodi system with this for both fresh and salt water. Any information would be greatly appreciated.
