Could you better explain what is wrong? Not being able to tune a wave is not a technical issue I can solve. I can fix a broken pump, controller, or power supply but if it is working as it did in your last post, this isn't something I can fix. It comes down to tank layout, dimensions, position of overflows and patience in tuning and set up. The wavebox does take a fair amount of patience to get tuned, it can take 2-4 hours of tweaking the knob to get the maximum wave and if you have corner overflows and live rock on the side walls of the tank, 3/4" wave height may be the best that is possible.
