How long do SCWD units generally last? and can you clean them to extend their life span. I was looking at the RIO 360 degree rotator (I know PH specific), or the SCWD. Which unit has the better performance and longevity?
I would stay away from anything RIO. You can put any size pump on a SCWD. If it ever gets clogged with dino's I will remove it and rinse it with hot water. Pipe it with PVC to keep the light out - less algae.
