Hi there, I will be setting up a 60x24/26x24 inch tank (LxWxH) not sure on the width yet. It will be 500-600 litres. I will need a chiller which will take up about 24 inches off the stand. I want to leave an extra 6 inches for a small ato and then I plan to keep the rest of the things on top of the chiller. So, I have about 30 inches of length area for a sump. I want a BM roller mat (probably large size) then a BM Curve 9 elite protein skimmer (I want some place for the reactors in the chamber with the protein skimmer. I plan on running carbon in the beginning and then Kalk (as it will be mostly lps corals) and gfo (if necessary). Then I want some space for a refugium, I do not plan on adding chaeto unless I need to do it will be semi cryptic in the beginning. Then finally the return pump which will be Maxspect Jump 8k. So what do you think of the sump? I know I don’t have a picture yet, but do you think I will need anything else? Is this enough? Will I be able to fit all of this in a 30 inch long sump? Will this be enough for a tank if that size? Please let me know, thank you! I will design a sump after I get the replies on this thread and then give a picture for you guys to tell me if it is ok or not! Thank you so much again!
