plumbing with pvc

Hey everyone, Need some help with getting my full syphon tuned to get the system quite. The tank was already drilled when I bought it. Not sure what I'm doing wrong Will attach pictures and will greatly appreciate any advice! Thanks

Has anyone done a 3D image of their plumbing? Here is mine! Quite proud of it so thought I would share. Took about 5-6 hours. Everything is drawn to scale All the pipe is 1” hard orange pvc. Interested in other people’s designs, 3D or 2D!

Hey there so I’m setting up a 125 display tank and plan to design the plumbing and have already made the sump. I decided to make a graphic in photoshop of my design and need some help on what I could do better or what could be wrong with this design. Never had a tank with a sump nor this size...
