55 Gallon Water Preserver Concentrate (5 years) Water Treatment Drops - Water Treatment For Drinking Water - Mayday Emergency Drinking Water - Defiance Fuel Water - Earthquake Water, Emergency Storage

Easy to follow direction. Product works well. We use on all are water reserves.

If it does what it says good value and nice sized little bottle for what I needed.

This item is great for storing water for long term.

Good for water

Works great but a bit pricy!

Came in handy sooner then I thought we had a storm that effected the water and I had already filled up gallons of water definitely have to get another bottle

Convenient and easy to use this extended-time water preservation liquid. All I had to do was count 8 drops of this chemical for every gallon of water. This stabilizer was used with a Waterbrick that holds 3.5 gallons, therefore, I used just 28 drops per container. I now have 70 gallons of drinking water which will be good until March 2030.

These are pretty powerful drops. I have not quite gallon jugs and use only 2 drops after I have cleaned the jug with super hot water. I put the drops in carefully and then fill the jugs with super hot water and then leave it for a couple of days. Putting more than 2 drops makes the water taste chemically. I have discovered the correct amount of drops and have great tasting water now.
