Ok I will help you out with everything. I am new to the reef so I feel like my setup was the easiest you can do. First i have a mag 9.5 return pump in my sump. I have a union fitting that is screwed onto the threads of the pump. This allows me to unscrew the union fitting from the pump so i can take the pump out if i need to replace it etc. without having to replace the plumping. From there i have a little converter piece that screws into the union valve and has threads on one end and is smooth on the other to allow pvc pipe to slide down into it. From there it is about a foot of pvc pipe and on the other end of the pvc i have the same piece i had on the bottom that the pipe slides into and has threads on the other end. Then i have a check valve that allows me to control flow from the pump that is threaded onto the converter piece. On the top of the check valve i have a piece of plastic that is threaded into the valve and on the other end it has grooves to slide the tubing onto. I have about 3 ft of tubing that runs up to the bottom of the stand that connects to a bulk head. I put metal clamps on the hose so it doesnt slide off. Thats about as simple as it gets. The attached pictures go in order of how i described everything. I got all the pvc piping at Home depot for about 10$ and the tubing was the most expensive, it was a roll of it you have to cut and costs about 20$. There is a video i used on Bulk reef supply about how to glue the plumbing and i didnt have a single leak. I used pvc tape on the threads so i didnt have leaks where it wasnt glued. I believe my threads are 1" diameter. I had some guy at HD help me find all the pieces that fit so i didnt have to make mutliple trips and because there is so many pieces of plumbing. If you have any questions let me know i would be more than happy to help you out. I hope this helps explain a little better for you.
This picture is the check valve? Where did you get that check valve at? I also got a Mag 9.5 coming in the mail today and hopefully I can start this plumbing today as well. Could you make me a list for Home Depot of what I need to make it a little easier.
Example: three 1" male ends ect ect ect......
If you remember the size of the PVC and clear hosing too. Thanks again. Your a big help. I just started myself last week.
