1. What did you use to separate the 3 compartments and are they glued to the tank?
Plexi and silicone--AGA silcone with NO MILDEW PReVENTOR
2. How do you get the water from the tank to the sump?
I am using a continuous siphon Overflow
3. Where can I locate that type of plumbing, I am think home depot has that stuff.
I got all the parts at Lowes (you will need to buy a overflow)
4. And finally, what is that light? Looks like a regular work light with clip on.
Yup regular clip on work light (the bulb makes the diff-see pic)
I notice to have no connection from the inlet and return pipes. What did you use to connect them?
This was "pre water" so the return was not set up (see new pic). It has a union on it so I can remove the pump without the plumbing for cleaning or pump replacement.
I got a lot of my ideas from Mel. If you want to do this you MUST research al ot to build your own correctly.

I used his closed loop design for my return (I am using a SWID on my return). Just make sure you read then read a bit more. Your sump must be designed right to keep your house dry. The overflow, pies and some tank water will drain into your sump if you lose power. You must build your sump to hold that water. You must also allow your return section to run dry and have your tank hold ALL of that water to prevent your tank overflowing. Lots to think about but it is not as hard as it all sounds. Just think it all out and ask lots of questions.
