I was wondering how to setup a side sump since I'm unable to have a overflow for sump would I need a pump into the sump and out or I read about a siphon overflow but I feel like the return pump would take up all the water and everything I'm reading just keeps confusing me so if someone can set me start I'd really appreciate it.
 
A sump on the side of the tank is pretty much the same as a sump directly under the tank. You just run your drain lines a little longer, a few more bends, so they can turn a 90 and go into the sump on the side of the tank.
 
Your question is a little confusing.
You always overflow to a sump (unless you are putting the sump above the tank).
With a sump, water flows to it by gravity, so you only need to pump water from the sump to the tank (never out of tank to sump)
Over flows can be from the side, the back, even the front, and overflow bees can be placed anywhere.
I have had some sumps right next to the tank, But in that case always have it placed slightly lower than the tank to use gravity, here is an example where a tall tank uses a shorter tank abutting it for a sump, the tall tank is 24" tall, the shorter one is 12" tall.


as you can see, an overflow box hangs on the tall tank, and is wedged and sits on the edge of the shorter tank. The pump sits in the shorter tank, and pumps water back to the taller one.

I see what you guys are saying but I'm concerned that the return pump (which is really strong) will take up more water then the siphon is able to provide, is this a valid concern or not?
 
The siphon can take whatever the pump pumps, as long as you have the proper sized U tubes, or if you drill the tank and provide proper sized piping.
I usually drill my tanks, and use 1.5" PVC. You can get overflow box U tubes with 1.25" inner bore.
For anyone to help, you need to provide the GPH (or GPM) your pump is rated for.
I usually use pumps with 2000+ GPH on mine, and if the flow is too strong, throttle it back with PVC ball valves.
 
"siphon tube", "siphon overflow", not sure what you mean by that. You need to tell us some information about your setup.

1. You just told us the pump output is 1325.
2. What size tank?
3. What size sump?
4. How many drain holes does the tank have? 0? 2? 1? Gotta know that, decide whether you're gonna drill more holes, or maybe plug a hole or two.


Looking at the pipe/drain chart in the link, 1.5 inch PVC pipe will drain 1400 GPH. I'm certain that others will post and say that they have 1.5 inc PVC and it drains well more than 1400 GPH.

I think 1 inch is a little small for 1325 GPH, so if you only have one siphon drain in a Herbie setup, 1.5 inch will work. If you have 4 drains drilled, they you should go with reducing bushings and 1 inch PVC on 2 siphon drains--use the other 2 drains as dry E-Drains.
