Will this sump modification work?

I have my tank for a little over a year now. It is a 90 gallon fish only tank. I purchased it form my LFS they came over and plumbed it as well. The way it is set up now is that my overflow box is at the left of the tank about 5 inches from the corner. The water exits through a megaflow overflow to my sump which sits under my tank. The hose actually goes all the way across the length of the tank to the right to make it from the display tank to the sump. It first goes into a bio chamber, then into my Rio pump to the Nautilus Te skimmer. As the water makes its way back across going back left it goes through a mag pump through a Kent U.V sterilizer and back up to the tank. I think the way it should have been done is that if my sump were just turned around then the water would not go all the way across the length of the tank which is btw VERY VERY noisy, rather directly down into the sump since the bulkhead that it is plumbed into would now sit directly under the overflow box. I am posting a pic of my set up as it is now.
1) I want to turn the sump around and plumb a short PVC pipe with a ball valve between the overflow and the bulkhead that goes into the sump.
2) Remove my U.V. sterilizer and drill it into the stand directly opposite of where it is.
3) Have the water go into the sumps bio chamber then into the skimmer like it is now.
4) Instead of having a plastic hose come out of the top of the sump to my U.V. Sterilizer I would like to plumb it with PVC through the bulkhead that is on the side of my sump that is currently closed.
5) I want to slow down the flow from that mag pump to the U.V. sterilizer so the water can pass very slowly through the U.V. either using a ball valve or a new pump, if using a ball valve will damage the pump.
6) Then plumb a plastic hose from the other end of the U.V. to an external pump which will be connected to my return line in my overflow box.
7) There is also a glass cover available for my Oceanic Model 2 Reef Ready sump that I will purchase to cover the top to eliminate all of the noise.
8) I will have to get part of it cut by a glass place to fit the Nautilus skimmer through the top.
******I need to know exactly how to plumb, what to use; adapters, connectors, glue, pipes, hoses, pumps, valves and most of all comments & feed back.
I need all the help that I can get, if the project isn’t too expensive then I will do it this coming Sunday and post pics to keep you posted.

I follow everything but this...

Your pumping in (mag) thru UV and then "into" another pump...???

Well I realized that wouldn't work, I would just use one pump. Anyway I could not get my sump out and cracked it while trying. It is only a hair line crack so I guess I will have to fix it tomorrow. For now all my machines are off untill the morning.

Well this is what I ended up doing. Got side tracked a little when I CRACKED MY SUMP. Fixed it first before I was able to continue. I used a an elbow and a union to connect the drain to my sump. I also purchased the hood for my oceanic model 2 sump, then took it to a glass place to have it cut to fit around my skimmer. The point of the project was to reduce noise and it did. My 90 gallon sound like it has a little hob aquaclear filter but really theres a whole lote more than that.

A Sand filter like a fluidized bed filter or natural biological filtration of a sand bed...?

Some of it's kind of hard to see in the pics...
In your first post you were trying to re route and slow the flow thru the UV...How did that go...?

I was trying to reroute the drain mainly and that went ok, you can see the way the sump was turned around and plumbed with pvc. As per slowing down the flow through the U.V. it wasn't my main concern. The tube form the pump to the U.V. is a little longer now so I guess it slowed down a little. What I really wanted to do is make it quiet and I did by replumbing it the way I did, and puting a glass top on the sump.

Sort of something like this pic except that it is totally closed. The water would not drip out like this thing it would get pumped through it, like the way it does though a U.V. Sterilizer.

I have the same sump, did it make a big difference using pvc over the standard hoses? i know the lids help with the noise. why didnt you put a ball valve in line after your pump to slow the flow into the uv? just curious what size pump you are using?

I am using a mag 12 and I am probably going to put in a ball valve very soon because the pump is to powerfull.

not yet, i am setting it up this weekend and im unsure if i should get the pvc or just use what oceanic supplied. my tank is 180 with 2 overflows and im using a mag 18. any thought on using 2 smaller pumps one to run thru the uv like a mag 12 and one for the other straight back return like an 18?

You can split the 18 with a t and just have one end go through the U.V.. If you are god with PVC then go for it because the hose they provide is very noisy.
