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

Great to use for a 240 gallon water storage take. After two years, I do not see any algae buildup on tank walls. Too bad the price has gone up from when I first purchased it.

I have bought these several times. I pour them in my 50 gallons drums when I fill them during hurricane season. They smell like chlorine. Not sure what’s in them but they last a long time. I had them last 6 months.

Thank you. I truly needed this.

Purchased this product to treat emergency water for storage. I guess/hope it works. I am relying on it to work. Hopefully, my family will never need it. It has a very slight chlorine smell but I think that is normal for any kind of water treatment.

great additive for storing water

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

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.

This item is great for storing water for long term.
