I came home and saw a flashing red / green light coming from under my 55 gallon tank - it has had a Vortech MP10 on it for about a year. I opened the cabinet door and saw it was the Vortech controller... investigating further, I found that the fishing line on my fish trap had fallen into the water and had been sucked in and wound into the propeller on the Vortech. Power off, gentle pull to extract the line, power on & voila! Amazing...
