I rode around the lake today (Friday) as I normally do daily and AGAIN, for at least the second time this week, the first thruster in "the dip" is not functioning. I am sure it is plugged up again. Just think about it, that motor is supposed to pump the water forward in order to keep the water moving and stop the collection of the algae blanket on the surface. In order to move the water it must go through the pump and the water is full of filamentous algae, a stringy slimy mess. The cage around it has been reconfigured twice that I know of and it is still the same problem. It will continue to plug as long as the filamentous algae is present. We have replaced that thruster once already and undoubtedly we will fry another one. Add to that the manhours we are burning with the guys out there in a boat trying to clean the cage so it will pump again. It is an expensive and futile effort. Frustration doesn't even cover the feeling.
