I mix CS in my cat's drinking water which is tap water run through a Teledyne 
faucet filter. It almost always turns color immediately on adding the CS to the 
filtered water--sometimes grey, sometimes lavender, sometimes pink. Never seen 
red, unless by faint red, you do mean pink? Wonder why the color it changes to 
isn't always the same color?

  I usually wake up a couple of times in the middle of the night and drink 
water. I run tap water through a Brita filter. In the last 6 months or so I 
have been adding CS to the glass of water that I keep by the bed. Last night 
the CS turned the tap water a faint red color almost instantly.
