Anyone know the limits to this? Is this true just for AquaMira, or for all Cl02 products (pills, KlearWater, etc)?
The above is true for Aqua Mira, KlearWater, Micropur and other chlorine dioxide products. The active ingredient is the same in all cases.
I've used about 1/3 full dose when the water will sit overnight. Following the inverse rule in principle I could have used 1/16 dose for an 8-hour dwell time. I'm reluctant to go this far.
Not an expert, but I wouldn't get too scientific about this. Methinks you would need some minimum dosage... in other words, 1/2 the dosage and double the time works... but would 1/16th dosage really kill everything -- even with 16 times treatment duration??? Another factor to consider is that once the oxidation finishes, any further "sitting around time" will probably be useless.
1) Product gets used up. Need minimum amount per volume of water. 2) Product deteriorates. You have enough product, but it loses its effectiveness before enough dwell time has elapsed. 3) Product escapes. Enough time, enough product, but it evaporates away or diffuses out of the container before the job is done. 4) Product separates. Like oil and water, eventually the product separates out before it does its work. Possibly remixing periodically would help.
Methinks this is where pre-trip inspection comes in -- as with all other gear pieces. Make sure the chemicals are still in good order, that you have sufficient quantity on hand, and that the container(s) are tightened up. Klearwater aside, I don't think you should be pre-mixing chemicals in advance.
5) Things I haven't thought of...
Yes, definitely. Once you use up your current batch of chemicals, switch to Micropur! A lot lighter than liquids, no worries about leakage or spillage, and no fussing with counting drops, pre-mixing or wasting time waiting for pre-mixing to finish. Just drop one tablet per liter or quart -- it's also easy to break a tablet in half when needed.
Micropur has a higher concentration of chlorine dioxide -- which allows it to label its effectiveness against bacteria, protozoa (crypto) and viruses! Normal treatment time is same as the others -- 15-20 minutes -- but up to 4 hours for water that's just above freezing. But if you read your Aqua Mira label, it mentions ONLY bacteria! Per another poster who talked with A.M. -- their liquid solution is weaker but should still be effective against viruses and protozoa if given a longer treatment time -- but they are not allowed to advertise or label about these two classes of baddies.
