Essup, Is this the ant-vortex device you're referring to? There is no vortex as it flows into the pipe. This thing works great. No trash washes in, nor whirlpool effect. I'm glad I listened to the engineers in the size of the intake pipe needed!
Fish are biting well when the water settles after the 3"+ rain dumps we get.
Note: The 2nd pic is full pool level on the AVD.
