feed cycle duration?

[marc nichols]

I've been feeding our 75g reef just before lights out; aminos, Phyto & zooplankton. How long should I keep the system in feed cycle (does not circulate through my sump & filters)?

8 minutes.................That's how long I can go just watching corals eat before I freak out thinking I'm going to go to bed without restarting the system again.
