I will take a pic later, but the level only goes up maybe 3 inches or so when I pull the plug. Most of that has to do that I drilled a 3/16 anti-siphon hole in my return just below the water line in the main tank. And speaking of the main tank, it is only a 29 so if my calculations were correct I am dealing with less than a gallon of water in a power out situation. The sump is 10 inches tall and to give you a sense of scale the baffles are 8" tall. When I pull the plug to feed it does fill to above the baffles but it doesnt overflow the sump. Like I said I will take a pic later. Right now I gotta jet to Home Depot for 3/4" self-tapping machine screws. I love DIY!!!
