I was pretty accurate with the hand temp thing too, when i put the water straight in the tank through the python. My fish looked at me like whatda?!?!?!!! if someone flushed a toilet though. :P
But sense i'm filling a 30 gal. trash can, I just toss the floating themometer in when i start filling it, then check it with a few gallons to go and adjust it, if needed.
What i read the other night from my Aquarium Atlas vol.1 pg. 905:
"2. Chlorine. Free chlorine is highly toxic. Just 0.1 mg per liter can prove fatal. It attacks the gills, leading to a loss of color and death through oxygen starvation."
