i cant tell from the pic with the level....but is the tank lower in the back or the front?
its just slightly off from perfect.....but if the tank is slightly lower in the back then i wouldnt worry as much since water will be flowing into the overflow.....but if its lower in the front then i would get some shims at HD or lowes and raise the front slightly..

Those pieces go on the bulkhead coming from the overflow to the sump. The coupler slips over the larger of the two bulkheads. after the coupler is a "Y" split. On one side is the hose barb that goes to your skimmer. The other side goes into your sump. The second piece of PVC (with the holes in it) slips over the end that goes into the sump. I would slip a small filter sock over this piece to cut down on micro bubbles.


I might have a picture of how it looks when it is set up. I will take a look for it when I get home tonight and post one for you tomorrow if I have one.

sorry to hear that the 5 gallon tank had a crack in the bottom, was it a large crack. It was fine when I cleaned it out a couple of days before you picked it up. It held water when I was cleaning it.

The tank is lower in the front - slightly. I'm not worried about overflow off the front but rather stressing the glass.

It looked like a pressure crack in the corner. Dont worry about it. Ill sillicone it and find another use for it. I like to keep things as automated as possible so I probably would have used a bigger container for topoff anyhows. Should I still use that setup ( the y ) if I am gravity feeding my skimmer? Will it cut the flow down too much? I plan on having a line from the train connected to a Tee, with one part going down to the skimmer and the horizontal part draining into the fuge ( with the ball valve whereever it is supposed to go - i have to go and look at some gravity fed setup pics ). I'm not sure how that section would fit in. Ok so I found out thet skimmer inlet is 1/2". How does that change my plumbing?

you can always go with new plumbing to fit your setup...
this is a sample of a drain for feeding recirc skimmers...
i think this design maximizes the crap getting drained into the skimmer....

That is pretty much exactly what he has.

When I set that tank up, my plan was to have the drain feeding both the skimmer and the fuge, but the space under the stand was kind of tight, especially with my large ass skimmer in there.

By the time I took the tank down, I had abandoned using fuges anyway, so it was no longer a problem for me.

Thanks for the drawing. Rather than draining into the skimmer section I wanted the other part draining into the refugium, which is on the opposite side of the sump, so I will have to adjust accordingly. Where do I put the valves and what type of valves should i be using? also - threaded or solved pvc joints?

Ok how does my schematic look so far ? It is not to scale. Now, along with suggestions on correct placement of valves and unions ( I did put a valve and union on the drain to the fuge in case I have to cut back water draining there as well for mantainance or whatever ) I also need to know where I am supposed to put bushings, couplers, reducers, etc. Also, when I measure the bulkheads and pipes, do I measure the inside diameter? What do I use to connect the pvc to the bulkheads? Do I solve the return and standpipe inside the overflow as well? Does it make a difference if I use schedule 40 or 80? Any specific brand of primer and solvant? Do I solve the skimmer pipes or use silicone?

Is skimmer going to be placed outside of the stand?

The problem that I see is that you have the water coming from the overflow down into a "T", with the side of the T flowing out to the skimmer. You want the skimmer to be at the the bottom of the T and the fuge being fed from the side of the T. This will make sure that you can feed water consistently and in a controlled manner to the skimmer. Turn the sump around if you want to lay it out that way, with the skimmer on the left hand side.

The skimmer will be outside the stand. If I had it in the sump, I would only have the smaller section as a fuge, at which point it would probably be more trouble then its worth. I will turn the sump around as per your suggestion and have the skimmer at the bottom of the tee. How about my pvc questions? Any advice there? I noticed that your drain used a rubber connection to increase the diameter (I'm not at home now but I believe it was 1.5" to 1.75 " ) - why was that? Is the rubber connector the best way to go for the drain and return ? Should I stick with 3/4" for the whole return plumbing ? What about the drain? Should I also increase that diameter ?

Note that skimmer is outside of sump and the drain pipe will lead vertically to the skimmer ( not as shown in picture ).
