Looking good. There is a problem with your overflows though. You need to figure a way for air to get into the down pipe or it will cause the display water level to rise and fall, burp and gurgle. You could try a length of air line shoved down into it. or on the outside 90's (where the water will come out and go down) drill a hole into the top and thread a 1/4" ball valve into it.
