ok the 2nd drain pipe (in the center without the filter piece on it) seems a wee bit too tall to me. Is that the 2nd or the emergency pipe?Thanks, I've been fiddling with it since getting to the office and a bit more optimistic. I thought keeping the emergency drain "dry" was imperative, and watching the levels go up and down was nerve wracking (understanding that whatever tweak I could make to the valve to keep it steady would only be temporary due to changes in flow over time).
Here are some videos of the tank running today.
First video is with the settings left from yesterday. Had to redo the valve because it was going crazy in the back and shooting bubbles everywhere in the sump.

Second video is cranking up the return a bit more to increase flow for the RFG, and also loosening the gate valve a bit to account for the increased flow:

Third video is after tightening the valve just enough to make it overflow the E-pipe, which is where I have it at right now. After turning it off and on a few times, it looks like it is running relatively stably. It goes up quickly while the standpipe is still gurgling and then initially dumps a lot of water into the E-pipe until the standpipe stops gurgling and presumably forms a siphon. Then it goes back to just trickling over the top for now.

edit nevermind. it is the emergency drain. so the third hole in the overflow you have plugged. any chance you can turn that into a secondary drain? have 100% flow through your primary 50% through the secondary and none through the emergency?
