I'm planning out my IM INT 200 Peninsula tank with a Bashsea Pro Series 48 Sump. I'll be breaking down an old RSR 250 and have an extra COR15 I can use as a lower flow to target those protozoans. I'll have the COR15 in my skimmer chamber that will connect to the UV sterilizer and back into the return chamber where a RS ReefRun 900 Pump will be the main return to the DT. That will be my option 1. For option 2, on algae and bacteria targeting, I'll turn off the COR15 and open/close the gate valves so that the RS Pump will go through the UV and into the DT. I need a good sanity check and making sure I'm not making this as complicated as it needs to be.
