The fleece compartment in the Fleece version of the Step takes up enough room that a dedicated return chamber in the smaller ones would make the return compartment too small. That said, the lack of a return compartment in the smaller ones will have no impact on salinity or an ATO. My sump in my system is 90 gallons. My refugium is 90 gallons for a total of 180 gallons. My return section maintains the same level as the rest of my sump but is at the end of the refugium. My ATO floats are in my main sump upstream from the refugium and my sump level never waivers nor does my salinity. The larger volume of the combined return section means a more stable and less turbulent return area so I don’t see a real downside. Now it’s possible that the larger Fleece Step Dreamboxes might accommodate a separate return compartment. I’d need to defer that onto Klaus but based on what I’ve seen thus far, the return compartment would end up being very small and turbulent if it were divided.


That said, there is also a filter sock variant of the Step. Not just the fleece version and that one does have a seperate return compartment since the intake compartment with the socks takes up less space than the fleece compartment.
