Overflow flushing making my sump level fluctuate
I just set up my 65 gal and my overflow keeps rising and lowering. Its also flushing like a toilet. Im worried because its lowering and raising the levels in my sump and I don’t want my ato to keep filling. Ive read a few places where they say my drain hose may be to long, so i cut it down to an inch in the water. That didnt solve the problem. Does anybody know why it would be doing this. Thanks for the help.

You can add a ball valve to control the flow into the sump but what I think you need to do is change the U to a T fitting
 Similar to this style with a larger outlet for the air Sent from my iPhone using Tapatalk Pro

That's a standard DURSO style drain. It appears to be 1" pvc? If so, the MAXIMUM flow you can safely (and quietly) put through it is 300-350gph. 250gph is even better (quieter)
It will help if you put a vent hole in the top like is shown in the above diagram. It will work best with a length of airline tubing inserted through the hole to someplace in the middle of the down tube. Where, exactly, will require some trial and error. Adjust it slightly, allow a few minutes for it to equalize, and then if needed, adjust it again. Keep doing that until there is no flushing and it is as quiet as possible.

You have the top elbows backwards. The one with the two holes and the little vent clear tube needs to be inline with the down tube.
Never put a ball valve on this type of drain. You need to put the valve on the pump to bring the flow down to match the drain after you make the above adjustment. You will probably only get 500-600 GPH with this type of drain but this is all dependent on the plumbing size and how it's run above and below the waterline in the sump.

Also the water level in your sump is quite high. Be sure there is sufficient empty volume to accommodate the water that will drain from the main tank when return pump is off.

Buy a DC return pump, that way you can match the flow with the drain.
