how low is the water that your return pump is sitting in? is it sucking air?
what is the plumbing like that returns the water to the tank? how deep is that in the tank? what are your baffles like on your sump? do you have bubble traps?

Ok, I fixed the micro bubbles, thanks a lot! New question, I had to restrict a lot of flow to the tank with a ball valve to get the tank to run smoothly. If I added another siphon to the overflow box, would that increase the amount of water going to the sump therefore letting me open the ball valve some more?

i dont fully understand what you mean. if you add another U-tube to the box, the box itself may overflow because it cant handle all of the water flow.

If mermory serves, 1" dia U-Tube can drain up to 600 GPH. If can apply another U--Tube, should drain more provided another flexible hose added to assit in draining. Rather recommend another overflow box to ensure that you will not have water overflowing from tank. And also 2 overflows will work as back up to each other, not to mention more circulation ib the tank w/o worries. Can Tee of and by pass some water to other equipment/refuge as others have pointed but not back to sump. Why waste energy when could utilize to its maximum capacity.Check my dwg which might help in resolving air pocket in U-tube. Good Luck!!.
Pardon my handwriting and terrible DWGs..

Hmm, interesting idea cerianthus. I'm going to look into that. Onefish2fish, you mentioned bubble traps earlier. How do those work and where do they go?

bubble traps are extra baffles in the sump.

I dont what baffles are either but thick foam can remove fine bublles as water passed thru it ( Largest Aqua Clear Filter Foam).

Baffles are the walls in the sump, if you look at the pictures in here there is 3 baffles in a row, this is a "bubble trap" the water flows over then under then over again helping to stop bubbles from returning to the display.

Adding foams, pads, filters or anything of the sort causes problems in saltwater as the collect gunk and detritus increasing the nutrients in your water, i personally would not use them or if i did clean them daily or every other day.
