why is my water level in my DT not raising?

I wouldn't worry with the water at that level, but the pic looks like the tank is unlevel, the water on the left side looks higher than the right side.

Don't use electrical tape. Go to a hardware store that carries acrylic sheets for sale. Get one that is at least as wide across as your overflow and maybe 4"-6". It seems you overflow is curved, so get the thinner grade acrylic sheet so you can bed it along the curve. Or even a thinner but semi-rigid plastic sheet. Cut it to size, then silicone it in front of the teeth at the height you want for your water level. Make sure it is level left to right. The good thing about silicone is it will not "bond" to plastic nor acrylic, but it will hold and seal it in place, while the water pressure in front will keep it pushed against the overflow. That way you can easily remove it with a little bit of force should you want to without breaking anything.

I did that with one of my plug&play smaller tanks, and I just happened to have acrylic sheets. Come to think of it, you can probably use any piece of flexible plastic, and silicone that over the lower half of the teeth.

The pump that I have is definitely overkill for the tank already. The only thing I can do to the overflow is raise and lower a gate in the front of the overflow. I have tried it both ways and there is no difference. The sides and 2 teeth in the front stay open with all other teeth closed when the gate is up. I also raided the pump to 1321gph and had a major sandstorrm in the tank to see if that would raise it. Its incredible if I need a bigger pump to raise the water level. the fish would be pinned to the glass!!

It doesn't make sense that raising and lowering the gate on the overflow would not adjust the level of water in the tank. I haven't seen this particular gate, but maybe it isn't installed correctly. The water in the tank should be exactly at the top of that gate no matter where you place it.

My suggestion was to only use it to determine where they wanted the water level, then get a piece of acrylic and make a more permanent install.

Well it is to the top of it, and falling over the edge when it gets there.

You would have to block it off, INCLUDING, the discharge cutouts on the L and R side.
