Re: [Killietalk] What's in my water

[Scott Davis <unclescott at prodigy_net>]

Aren't magnesium and calcium needed for proper
skeletal and neurological development? How does
Potassium figure in?

Thinking of the old Far Side Cartoon, I like boneless
chicken, but don't think I'd appreciate boneless
killies.

Also, speaking of balances in the water, if the water
just had sodium chloride in it, would the fish lose a
percentage of their other mineral salts?

Edd, that's a good question though. One can hardly
open a book on aquarium fishes without the author
suggesting "add salt."

Prolly should add some salt if one is keeping
estuarine killies or sail-fin mollies. But for
breeding killies, "one size fits all" works no better
in terms of water than it would for AKA convention
t-shirts.

All the best!
