Having the overflow going into the reservoir, might have an issue of detritus settling out. I've tee'd off one of my drains into a separate refugium and since no filter sock, skimmer etc and BB, know it builds up so forced to siphon it out everyone and a while.

Reason asking about the standpipe is am interested in running a Herbie without an overflow chamber. Like the idea so I've played around with a 33g and a 1" bulkhead and seemed to work okay. Biggest thing was getting the height of the standpipe correct so the water level was where I wanted it. With only ~230gph found I had to have the standpipe 2.875" lower than the bottom of the trim (final level was going for). I had suface agitation and still worked okay but nothing like a surge device.

I'm with you there.. I don't think any off these ideas are mine just reused in a different way.

I do plan on running a filter sock as well but I don't know where, the reservior sounds like a good place. on my test with a full load of water the noise level was great, When I spoke with Mike at Hidden Reef he felt that the 1.5 inch pipe would be large enough to eliminate any noise issue without having to install some type of silencer. It works well, but like I said that was with a Mag 5, not the Mag 18 I plan on using.
