Untamed & Blaster,
I have the opposite end of the union attached to a bulkhead fitting in the side of my sink.
One set is for siphoning the tank, one set is for vacuming the sump.
Since the sump is too low to start a siphon one was made seperate.
It was just attached to the intake of a mag 5, so i could suck it out, but then i can still use the same union on the sink.
I just did it this way so the line stays in the sink when im pulling on it all the time as i walk around the tank with it.
I made the union high enouph in the sink to use a gravel trap before entering to the drain.
Mark,
Unfortunatley i didnt take pics of mine, maybe if jamie see`s this he can find a few pics of the same type of install we did on his window.
All i remember is like using 7 caulking tubes on the face pane....
Dual closed loop w/OM 4 way`s .
Ill put this one on as it still may help others with idea`s, but i no longer use this on the system.
When the tank was being built, i placed 10 holes in the perimeter bracing to accomodate 8 Closed loop outlets and 2 for the main system feed lines.
These were each a Sequence 5800 fed to its own Ocean motions 4way.
I didnt want these lines fed on the backside of the overflow, so the line ran back up through the overflows to the 4 way`s.
Some pics of that all being set up...
The loops plumbing had to bend so it was somewhat straight when it came up through the old walkway, because the walkway was still removeable at this point.
The outputs and the OM`s still had to all sit as flush to the tank so the canopy could slide in and out.
But the OM`s needed still to be at the high point of these loops, so when i did need to open the OM`s, i didnt have to drain the loops everytime.
I wasnt happy for long with this set up due to a couple reasons,
-Heat....3 degrees per pump difference.
-clutter...i hated leaning over on the plumbing while worked on the tank.
-noise...by far that was the noisiest part of the whole system.
as much as i loved the OM`s i dont miss opening them up either.
I felt as though this were also a weak part of the system, due to the fact the intakes for the pumps were low, and i had nightmares of a pump housing cracking or a pipe let loose...draining the entire system.
I also wanted a more permantent walkways that also wrapped around the side of the tank aswell.
I loved the movement it offered however, aswell as the "in tank" views was overall cleaner.
The substitute....
I opted to use wavy-sea`s with tunze`s attached to them.
Heres how i attached them together,
At this time a pair of waveboxes was also added, to help pick up detritus off the floor.
I am very happy with the change and glad i switched it, heat was drastically reduced, the system actually became more simple.
Aswell, combining the variable flow from the tunzes and variable movement of the wavy-sea`s made for the most adjustable and versatile flow patterns that i have seen.
Marc.
