cleaning powerheads w/ vinegar

[Matt]

What's this about cleaning powerheads? With vinegar? Why? I can understand taking the impeller out and rinsing out the gunk to keep them mechanically sound, but they look better (more camouflaged) with the coraline on, don't they? JMO, YMMV.

If you must (and I suppose you wish to), use distilled white vinegar. Pretty pure, so it's safest, and thankfully, it is the cheapest too. I mix at about 50:50 when I'm cleaning, but a lot less when I'm soaking something.
