So, I've got a 75 gallon tank that had been modified to be a sump (essentially 3 glass baffles to create the return "chamber". Are these needed. I'm looking at redoing my sump, plumbing and everything to be neater, easier to maintain, and fit more equipment. For my overflow rate, I'll probably need 2 Large Bubble magus roller mats (eliminating filter socks!). I don't have room for two filter rollers, my massive skimmer, and ATS unless I remove the three glass baffles. We have to drain the sump anyways to redo some of the plumbing and reposition the sump.
MY ATS is plumbed off my return pump, so, I was planning to run the ATS directly over the top of the Return area. Remove the baffles, move the skimmer to be in between the middle 3rd of the sump and move my heaters to be in between the overflow area and skimmer, and hard plumbing "Y" fashion splitting into two 1.5" overflows off of the primary into two large bubble magus filter rollers.
I realize ATO will be a bit odd at maintaining the level of the entire sump vs. just the return section. If I need a return section, then I'd probably end up shrinking the return section to be half the size it is now, and just use two custom made acrylic baffles.
I would prefer to just remove the baffles and control the overall water level of the sump. I've got a great ATO that can run my top off pump up to 99 seconds before shutting off as a fail safe. So, I think it could easily keep up with the level of the entire sump. My total water volume is in the neighborhood of 350-375 gallons (340g display and 75g sump about half full).
I've had this 75 gallon on multiple tanks for 8 years, and I'm ready now to go to the next level of roller mats vs. socks! (My wife is too.. she gave me the go ahead to buy anything I need to get rid of filtersocks going in the clothes washer. ) I'm pretty sure that's within reason...
