Hi, I though I'd ask this question on this group because there are lot 
of innovative hobbyists here that look for ways of using of the shelf 
items to achieve some goal.

I'm wondering if a salt water inline aquarium pump can be used for acid 
or etchant. I wanted to continuously filter a 15 litre tank at a rate of 
2 to 40L/minute. I own a small 10L/minute fresh water aquarium inline 
pump. It has a stainless steel shaft, and the magnet impeller has an 
exposed ceramic magnet. The wetted pump housing is glass filled 
polypropylene so that is resistant. The impeller blade is some unknown 
plastic, but its not nylon so it might be ok. Since salt water aquarium 
pumps use ceramic shafts and probably protect the magnet with plastic, I 
suspect it might be safe for acid/etchant. Its about a AU$60 gamble.

regards,

Adam Seychell
