[Killietalk] De-icer

["Gary Smith" <rivulus at cogeco_ca>]

Hi Everyone,
                   Today I went and bought some De-icer at home depot. I
could not find Prestone so I bought a brand from stone mason.It's called ICE
MELT with calcium chloride flakes. I plan to use this for Cyprinodons,
Aphanius and other pupfish types. There is no other ingredients on the
container so do you think this is safe to use? Also how much should I use? I
plan on adding a bit at a time and keep taking hardness readings until I get
up to the hardness I want. This de-icer is not in liquid form, but in a
granular "flake" form.
 What is the ideal hardness for these fish? I was thinking of somewhere
between 250 and 400ppm.All help is greatly appreciated!

Gary
