Hi all well I just got my sump yesterday from Hawiilipino and its all good. But after I set it up the pump seems to be faster than the overflow. I used the u tube and it was slow so I added another one and it still was slow. So I was wondering is I can use the front part of the overflow box ( the part in which is in the tank that takes in the water) and then use a utube attached with a tube directly to the sump to increase the flow?

And to aviod it from flooding. If I set the front overflow part to where I want it to and then the water lvl goes lower than it then the water would stop
 
What I think you're suggesting is a straight siphon to the sump.
If you are, I would advise against it becuase it will not restart after a power failure.
 
Well Im willing to restart the siphion if it grats me faster intake. But ya Just did it and everything is good to go. I tested it and when the water is lower than the front overflow part it stops. Doing it this way increased my flow alot and its been working out the past hr or so. But the one problem is that you can hear this loud sound comming from the siphion.
 
Welcome to the wonderful world of sump/overflows.
The sump part is wonderful. Hands down, the best way to filter a fish tank.
The various means of getting that tank water into the sump is what will drive you mad.
Skimmer boxes, “U” tubes, bulkhead fittings, overflow boxes, flexible hose…man, I haven`t even got to the assorted gurgle/slurp busting designs.
It won`t take you much time, before you understand why most recommend sumps be combined with drilled or drillable tanks.
Lot`s of way to tame your noisemaker. Look through the postings and stickeys, you will find enough to keep you busy for a good while.
Good luck to you.

Amen preach on my brother from another motha. I have ran a sump from almost day 1, I have changed the way I get the water from the sump to the tank many times. DIY PVC over flow, DIY Overflow box, Drilled tank, while the drilled tank is the safest there are still many options here. Bottom drilled? top drilled? Vertical or horizontal overflow? then you have the plumbing behind which will effect the flow rate; and like the man mentioned then you have too worry about noise. What I am saying is it took my almost 2 years to figure out what worked best for me, and I might next week decide its not what works best. But I would never trade my sump for a canister.
 
If I use a weaker pump then the sump will get filled halfway and then stop until the pump catches up.

As of right now The sump is filled 2/3rds of the way with the j tube in the tank 2inches below the water lvl with the water outside the box pulling in water. in which Im thinking if I add another pump it should balance out.

Do you mean overflow? The sump should work the same regardless of the water level provider there is enough water to cover the pump. The over flow should always be faster then the pump, you should be able to have your overflow pass 1000gph and the pump only put out 10gph and it should work just the same is if it where a 1000gph overflow and a 900gph pump. As the overflow will only flow as fast as the pump can feed it. If this is not the case something is wrong. Pictures would help.

Check-valve. Install a check-valve to the return and adjust until the inflow and return are equal
