So im finally taking the step forward and will be drilling and setting up the C2C overflow on my 65 gallon this week. I feel as if I have everything figured out except for the height of the weir. Below is a photo showing my current plan. The reason for one drain being lower is to help start the siphon faster as well and the fact that one of my bulkheads are from a different maker and therefor has a larger flange but all three are still 1" bulkheads. Would 3.75" of height be okay if placed a 1/4" from the bottom of the 90? I would like the water to sit about 1/8" above the trim to hide the waterline. Any help would be greatly appreciated
