I want to make a sump for my 125 and was wondering how to go about it. what kind of pumps, PVC, filter media, pads and whatever else I'm forgetting.
 
and do i need a overflow box if so how do you do that
 
Crap, those are very big questions. Your on the right site for it though, hopefully I can help without telling you to use the search feature lol

I have a couple (5) 125's I like to use as grow outs for my larger aquariums (big breath).

You need some kind of over flow box. I like to use www.glass-holes.com for my overflows. Super easy to set up and they don't take up valuable realestate inside your aquarium.
The sump is easy. I like submersible pumps, just drop them in the water and run a return line back to your tank, done. For the sump you can use a rubbermaid container. Run the overflow water from your glass-holes overflow to the container. Look up filter socks. Have the overflow water go into a filter sock for mechanical filtration then have it spill onto a bucket filled with bio-balls or scrubbies or some kind of bio media. The bucket needs to have holes in it to drain and force the water through the media. Then it flowes to the pump then back to your tank.
 
what size of overflow and tubing, and like one of those 3 draw rubbermaid
 
oh and i want to do this for a turtle tank
 
Well..... The flow is up to you. Some folks say 5 times the size of the tank some say more some say less. Check out glass-holes and pick an over flow that fits your needs and the pump your going to use.

I don't keep turtles.......
 
If you could provide us with a picture or more details on what exactly you're working with myself or others can probably give you more specific answers.

Sumps generally have a few sections/steps.

1. Physical/Mechanical
2. Biological
3. Return Pump/heaters/equipment

For physical you can do a number of things ranging from floss pads to micron socks etc, it really depends on what you want to do. I will make one recommendation though, make sure it's easy to clean or you wont do it and your pets will suffer.

Biological can be done a few different ways as well, scrubbies(cheap), bioballs(slightly more expensive), ceramic rings(more expensive), K1, and there are probably other ways that I haven't heard of. Biological filtration can be done in a few different ways, fludized beds, wet/dry, and wet filtration. I don't know much about fluidized beds, but from what I understand about wet/dry biological filtration and wet biological filtration, the wet/dry is more efficient than wet filtration, so if you can go that route I'd suggest it.

Some people also chose to run carbon, and if you do choose to go this route make sure that you do it right and run it actively. Run it in a media reactor such as the Two Little Fishies Phosban Reactor 150 with a Maxijet and you're all set for pretty cheap. There are more expensive options out there, but in my opinion they're not worth the extra money unless you've got a larger tank in which case I'd just suggest going with Two Little Fishies Larger Phosban Reactor the 550.

I'm not really sure how this would apply to turtles, but I do know that turtles are insanely messy compared to fish, so I'd suggest beefing up that physical/mechanical filtration and cleaning your sump more often than recommended to ensure that it doesn't turn into a nitrate factory as the waste decomposes.

He's got a ton of information on sumps and refugiums, but in your case you probably want to do more of a sump since I think you're doing fresh water and don't necessarily need pods(food) for your fish.
