I’m not sure if there is a limit or a maximum intake of treated water per day when using this pills, but on my last trip I was in the middle of Algonquin park and I had mixed 2-3 tabs in 2-3 litres of unfiltered water in a day for 5 days, without issues. I never got sick or had any stomach problems.
When I use this Aquatabs I’m looking for a running water stream from a crick, river or I fill in straight from middle of the lake where the water is mostly clear, without floating debris, and as per description, I drop 1 tablet per litre in my thermos bottle, shake, let it dissolve and neutralize the contaminants for 30 minutes or more and is ready to drink.
The taste is decent, has no chlorinated smell and I had great experience using them as intended to make drinkable water during portaging without worrying about bacteria or contaminants in the water found on multi days off the grid and they are very portable to carry a few as backup or emergency if on vacations to down south countries.
Overall, this Aquatabs pills were packaged excellent, good presentation with detailed instructions and precautions, all packaged in 2 sealed weatherproof and resealable ziplock bags with 50 pills each, individually sealed and has clearly stamped the valid expiration date until Jan 2028. Thanks
