I ran my wave pucks for a year straight with no cleaning and no issues. Great pumps, I have not had any issues with it locking up when putting back on the magnet.
well finally got my wave pucks mounted on the sides of my 60 gallon cube. Very impressed at how silent they are, along with the broad flow and the ability to direct them so easily.
They stick out inside the tank more than my vortechs but I like that i don't have the cords cable tied on the outside. Always hated that look. the next test will be longevity and how easy they are to clean when the time comes.
