Hello all. I am in need of help from someone who has a Red Sea Max S tank set up. There is the "ledge" frame that runs along the inside of the tank along the top. I found in the instructions that the water level should be below that ledge, however, I cannot adjust mine to be that way and as a result it slowly leaks at the top of the corners. I assume this isn't an actual leak, but is doing so only because the water level is above that ledge. When I adjust the valve to lower the water level in the tank, it gets too low for that overflow "box" (not sure what they call it) and the gurgling noise is insanely loud. The only time I have had it work (water level under the ledge) is when I took both circulation pumps out of the back chamber for cleaning, but I need the added flow from those two pumps, so when I put them back in, the water level rises too high again and goes over that ledge. How in the world do you get these tanks adjusted properly! Thanks.
