The level of water within the overflow is not that big a deal, unless it is very deep. Then if the level is low, water will make noise as it falls over the edge down into the overflow.
Mine is only about 4.5 inches deep, and as long the siphon is working the level makes no difference in noise.
Just barley cover the top of the downturned Tees.
If you ever want to run a wave box, make sure you have about 1.5" from the top of the overflow, to the top of the tank. When it's all working proper, the top of the overflow will be the water level in the tank.
