[APD] RE: copper safe and fish medicines

["Pete" <peteal at sympatico_ca>]

Talking about how certain medicines are hard on fish, some of these sound 
down right nasty, maybe even to us.

All if it is a good read, but some of the scary stuff.

- Wear gloves and goggles when handling malachite green or formalin. Do not 
inhale the fumes of formalin and always handle in a well-ventilated area. 
Both are potentially dangerous. Malachite is a respiratory poison as well as 
being a suspected carcinogen.

- It is likely that malachite green will be banned in the near future

- Formalin should be stored in the dark and above 40C to prevent the 
formation of paraformaldehyde
