The refugium and DT exchange waters using both HOBs (pump in one - overflow hole in the other). The pump in the DT HOB both moves water from DT and removes air (venturi) from the refugium HOB intake tube to ensure a syphon is active while it's pumping. There are emergencies in place; both HOBs can operate while off from a syphon; in which I should mention that the DT HOB turns off at night for flow reduction and the refugium HOB will be always off (excpet for emergencies - I plan to install a float switch to turn it on if the water rises too much - this will move water quickly back to DT as the drilled overflow in the HOB is under the tank's rim). There are anti-syphon holes in both HOB intakes at appropriate levels (in tanks) to prevent too much water from being moved into either tank in the event of line clogging. It is in the bedroom - it has been running with no sound
The over-head fuge went down to that lower tank (QT right now - intended as little coral fragging system - 20G [light mount temporary lol]).
Here's that entire area right now (almost all lights on for visibility):
Since the over-head 'fuge came down, I plan to add a second light over the right side of the DT finally
Oh yeah - I added this 'hidden' light bar from Marineland (blue and white LEDs) a few weeks ago to try to get more light over to the other side (before the old 'fuge was moved). It has helped a bunch; it will be staying here even after I add the other e26 light.
Also - the e26 bulb that was on this thing went over the 2.5G for a little and then to the .123G - the e26 bulb over the left side of this tank is now a 12W ABI Tuna Blue LED
The new 'fuge has four clear containers holding up a glass pane to provide a place to keep softies and other macros. Its overhead lights are not active yet (to run at daytime) - undertank light runs at night
Cup 1: rubble with perforated bottom
Cup 2: large particle sand bed and rubble with perforated bottom
Cup 3: mud with sponge and snorkle to allow the bottom to breathe
Cup 4: more mud sponge and snorkle
That larger shallow container on the glass has mud under coarse sediment - hoping to grow some rooting stuff there

Thanks for checking up on what I'm up to :]
