And I will type the reminder formula for passive settlement of solids. 15 minutes dwell time within chamber = 1/4 of the flow. 4500gph pump - TDH = maybe 3600?, means 1000g settlement chamber, something about 4 x 8 x 4. You seem to be planning about 1/8 of that so you should expect about 1/8 the results.

Buying the biggest vortex you can find/somehow pay for always seems to be the wisest path now that I have disappointed myself with the function of so many first chambers I have built.

Combining passive settlement with active mechanical separation is a better small footprint solution. Consider static K1 or some type of screen device.
