If I ran a closed loop, I would run them in series of that line.
Your point about the location of the swimming stage in the DT
I think the DT to sump turnover is close the 10x
Thoughts, comments
I’ve got 2 57w AquaUV’s
300DT, 40Fuge, 50g in sump

At what flow rate
Full automation....

I hope you’re maintenance and calibration procedures are top notch and religious!
By performing large and frequently
You immediately dilute the “pollution” and simultaneously replenish ion pulled from solution during biological processes
