You two are effing crazy. Don't come crying here when your tanks crash from "sudden low salinity". My rule is ATO container is no bigger than 10% of the system volume. If the ATO is full, the majority of the tanks' inhabitants will handle it (SPS may not). If I design the system, the sump will also hold this volume with the power off and not get the floor wet.
