WHat gph should I have,tank sizre is 300 galloons? I ve read 600 gph is good for the bacteria to harvest everything from the water.
Also the inlet piping is 1 inch so what should the outlet pipe be? Iam thinking 1 inch also.
Above tank application.
For the outlet I was worried about not enough flow over the matrix.

I highly highly and once again highly recommend you outflow be much larger then your inflow. The last thing you want is to have the water coming in faster then It can flow out, also with the outflow like you have in you picture you will get reduced flow rate so you will need to use even larger piping. 1" piping plumbed like you show will probably flow like 250gph to 350gph for your outflow.
I only have a 220 gallon with 55 gallon sump, I push about 600 to 700gph and have zero problems. Some people will tell you 10x Turn over some people will say 5c turn over, I think 2x to 3x will work fine. You can always increase it with larger pump or power heads provided your outflow can handle it.
as far as the matrix goes you can use bubble bars or a power head in the container to increase circulation, but alot of people just have a bag of bio rings in the sump, its more about contact time then how much flows through it. It works like osmosis, the water gets cleaned by the bio, which dilutes the rest of the water, this keeps happening till nothing is left.

Ok Ill just put the oulet at the top. Would a 6 inch id outlet work? This is for an indoors so I would hate for overflow.
Or would 4 inch id outlet be better?
Thank You nfored

Depends on the flow rate 4" would likely be more then enough, You could likely get away with 3"
If you put it at the top you can draw water from the bottom by putting a 90 on the inside, and putting a small hole at the top to be a siphon break. You don't want it to suck out all the water and leave you with dry media in a power outage.
In my setup leaving the tank and entering the sump is pretty much like your filter is, has two 2" horizontal overflows connected with a Tee to a single 2" pipe. The single 2 inch pipe can flow fast enough to keep up with my 700gph turn over without a siphon, but it must be feed by both 2 inch overflows to keep up. If one of my overflows clogs then the tank will overflow.

you could always do multiple smaller pipes, to allow you to distribute the water better also. Another thing to think about is bottom drilling the container rather then side drilling for even faster flow.
Good luck and I can't wait to see pictures.

It seems like both you guys are going way overboard with your drain pipe dimensions. If he's only going to be running 600gph, then he can get away with a single 1.25" drain pipe. If he wants to be safe, he could go with a single 1.5" drain pipe, or he could double up with 2x1.25" drain pipes.
And having 2x2" overflows that then combine into a single 2" drain pipe is going to flow the exact same amount as having 1x2" overflow connecting to a single 2" drain pipe. The pipe can only flow a certain amount of water, regardless of how many overflows open into it.
Look at this thread to get idea's for sizing your overflows and drain pipes:
