[pct-l] Aqua tablets vs drops

[Bob Bankhead]

Wrong. Five minutes is the time you let the two liquids to react in the
mixing cap (as evidenced by the development of a yellow color) before adding
to the water. 


>From the Aqua Mira liquid bottle:

1) Prior to treatment, clean water container.

2) Place 7 drops AQUAMIRA (Part A) and 7 drops AQUAMIRA (Part B) in mixing
cap. If water is cloudy or tinted, use 15 drops of each.

3) Let mixture react for 5 minutes

4) Fill container with 1 quart (1 liter) water. Add contents of cap

5) Shake to mix. Let stand 15 minutes. If water is very cold, cloudy, or
tinted, let stand 30 minutes.

6) Water is ready for use


Tablets say allow 4 hours of contact  away from sunlight to generate a
solution of 4 ppm chlorine dioxide. In reality, 30 minutes is plenty unless
water is very cold, cloudy, or tinted, or if you are trying to assure
destruction of protozoans like Crypto and Giardia.

I routinely give my water 30 minutes of contact with AM liquid since most
mountain springs and creeks are very cold. Protozoans are not an issue in
the Sierra and Rocky Mountains, but bacteria are - or can be. You never know
what is lying dead or pasturing upstream. Springs are usually safe
untreated, provided you are at the source rather than several hundred yards
downstream.

YMMV.

According to the packaging, the tablets require a longer 'set time' before
you can drink the water.  If memory serves me right, 4 hours for the tablets
vs 5 minutes for the drops.  Only problem with the drops is that the dropper
bottles sometimes leak, so you lose either part A or B (never seems to be
both!).
