I just purchased a nano wavebox from the trading/sales forum. It worked for about ten minutes, then it just stopped. I tried cleaning the pump to see if that was the problem, but this didn't do anything. Not sure if it's the controller or the pump. The controller looks like it is working. The lights are blinking from green to red, and the red light to the pump is showing that it's on. Any suggestions on what can be done would be appreciated.
