my new 90 gallon wet/dry sump piping

[Shaker]

So in the process of hooking up my new Craig's list 90 gallon tank. Just wanted y'all to let me know how my piping looks. I had to do as much piping as I can fit cause of how powerful my water pump is also put a t in the piping and directed it to the sump.

My overflow system puts down 600 gph " supposedly " and my external water pump puts 1,100 gph with a 22ft head at 10psi. So that's a big difference I guess once I get the sand and water in I'll. Balance the flow out using my ball valves. Doing a leak down test with tap water in the morning
