I'm looking to set up a overflow for a small sump to hide some equipment. If I am understanding correctly, if I put the return pump behind a baffle or into a small bucket, so long as the volume of bucket + overhead is less than the void volume, I shouldn't encounter an overflow if the siphon breaks in the HOB overflow? For my tank I think the void or headspace should be roughly 3 gallons which should be an acceptable level for the 10g sump I'm planning.
