I like having corraline all over my Powerheads. I like to remove my Powerheads every 3 months or so and give the internals a good scrub down. Is there anyway to do that without killing off all the corraline? That would suck.
I do the same. I dont think it hurts anything to clean it up. I have been doing it now for a year and no problems. As long as it stays on the rocks and back glass.
