Wanted: Koralia wave control

[Johnsbra123]

I have a 550 gph koralia and I here that these relates can slow down the movement and control them. If anyone has one laying around, just message me.

wave control will not slow down the flow, but it will timely control the power heads so it kinda like turn on and off power heads alternately.... City pets has some.
