Would there be any issues with the ATO if the water level was all the same in all chambers. The only thing I would think of is more filling time which shouldn’t be an issue with me. Played around and slept on this configuration for months- being the skimmer in last chamber Incase I need to put my bigger skimmer in later or any additional equipment if need to; won’t fit other way around (more use of space this way because of the roller mat, my bigger skimmer won’t fit sump being other way around). Will have either a removable sponge, acrylic baffle, or bio balls In-between pump and skimmer in case any micro bubbles. Any input it welcome
