Wowzer, you can dial down enough to notice the wave but not splashing the water out of the tank. Couple thing you can do to help getting bigger wave without having water all over your floor
1. lower the water level
2. Enlarge the overflow screen. How? cut it
3. If the return pump is TOO strong. Get a smaller pump like MJ900 - 1200. This way the water level will drop a bit to compensate the heigh of the wave.
If you want to make sure it is going to work before spending the money. Get a tubber ware container with similar dimension with the nano 6206 or a bit larger that is ok. Cut a hole on the side of the container to perfectly fit the pump nozzle, Cut the top of the tubber ware so you can fit your hand inside to mount the pump (I hope you have a small hand

). Once you have the pump properly seated inside the container, stick the container inside your AP24 against the back wall. Hook up the 6091 controller to the pump, have a friend, wife, son or daughter to hold the box while you try to dial in the wave....

. It is a lot of work but its fun :lol:. I think soon enough Roger will banned me from using tunze because i try to do crazy thing with it.
