K-meta binds with chlorine very fast to make it fall out as a salt. If you ever have to clean your equipment with bleach, you can always spray k-meta in after to get any residual chlorine you have left to fall out! It has the same effect in chlorinated water too.
I've not done the exact calculations, but about 1/16 of a tsp in 6 gallons should be enough to bind with all the residual chlorine from treatment. Again, if the water tastes good enough to drink, then it's perfect for kits. Kits were designed for tap water.
I'd encourage you all to google bottled water bacteria levels. You are going to be grossed out and very surprised by what they are finding. Tap water has very rigorous safety testing for bacteria, while bottled water is largely unregulated and untested.[/QUOTE
Dean, that's good information. A few months ago I filled a gallon jug with tap water and added some kmeta to it. I noticed the sediment and wondered what it was.
