That's interesting.

The only "metal" object exposed to water in Eheim aquarium/fountain pumps
is the magnet, they have a ceramic shaft.

But then, the pressure from those pumps is minimal.

Bad thing cole-parmer has N/A for lexan/polycarbonate (no data), But
Hydrochloric acid is "good" so i hope i'm ok.
I suggest always check for HCl too if you check for CuCl as it isn't sure
it's included...

Steve, do you know about lexan machining/gluing? Should i ask at
propmasters?
