a couple more thoughts: most of the beneficial bacteria we need for biological filtration attaches itself to substrate rather than free floating. Like when I start a new tank with Fritz bacteria it says to leave the UV sterilizer off for 5 days. After that the bacteria is 'safely' attached to stuff.

My main concern right now is bacterial stuff so I go at the higher end of flow rate.
I also dose live phyto. According to the flow chart it should not be killed off by this but I set the reefkeeper to shut off the main pump for an hour, dose to the display tank and the sterilizer is down in the sump so the tank gets live phyto unfiltered for an hour
