You could try it without the tee, since you're really just putting a small amount of flow through it, it probably won't matter much. Could always add the tee later.

Don't forget about the other option I mentioned regarding a straight herbie overflow with two back ups. Would look like this:

The other option is remove that third overflow pipe all together and close the ball valve. Run the piping after the valve to a hose or something you can stick in a bucket or drain. This way you can use it as a manual drain for draining your overflow and removing water for water changes.

I like this option the best. I would leave the second back up drain threaded so that if you wanted to drain the overflow to clean it, you would just un screw the drain pipe and re-open the ball valve to drain it. Would make for nice easy cleaning with the safety of redundancy

Hi FishyFishy

This is the original way I have it, all my bulkheads are slip fitting, the main line in the photo with strainer is with a gate valve, the center is not restricted right to the sump, the far pipe with strainer is the secondary has a ball valve.

I am ordering a T for the durso, that will slip in where the secondary is.

I designed this to be flexable.

From what I can tell on that picture you're only concern would be getting a full siphon and quietly enough on your main drain (closest in picture). If you either removed that strainer, or removed the standpipe and had the strainer directly attached to the bulkhead you would be good to go.

The height of the primary drain is not really a significant detail, it just has to be lower than your secondary trickle drain by a large enough amount that it will take a full siphon without sucking in air.

You can leave the strainer on the secondary if you'd like, as you only have a tiny amount of flow going down that pipe.

This is a great option. I have mine set up like this, except the left standpipe is 1/2" lower than the emergency drain. I have siphon on the right, emergency middle and a secondary "trickle" drain on the left. Since I have very little flow going down the secondary, I personally don't see a durso style pipe as advantageous to me.

Furthermore, I made full attempts to make an efficient overflow that pulls as much of the surface scum off the top of the water as possible. I feel that my overflows should also take advantage of this as a durso has the potential for scum to collect on the surface in your overflow still. I'm sure in the end it's an insignificant detail in the grand scheme of things, but I like to blow the little things out of proportion in my head.

I hope you don't mind Sphelps, but I edited your image to show how I run mine:

[scubadawg]

I purchased a Plastic plank from Home Depot which I screwed to the counter top, then used Carlon clamps used for securing electrical conduit

[scubadawg]

I ordered 5 - 4" X4" Corian Samples to be used between the leveling bolts and the hardwood flooring with felt pads between

[scubadawg]

I used Wiremold to run the Powerbar and Network cable to the left side of the Stand.



Sump is in place with 2 mesh filter socks

[scubadawg]

Poured 1 plus bucket of H2Ocean salt



Deltec Skimmer in place


BRS Carbon and GFO Reactor in place



JBJ ATO mounted



Apex Controller mounted, Power Supplies for the Sunbrites LED will be on the Top Shelf



Test Stuff



Water tested 1.026, ready to add Sand and Live Rock

Looking great very neat and tidy!
