For one Gallon, 12 Drops are recommended. To answer your question, 12 Drops X 5 Gallons = 60 Drops are recommended to store and maintain pure water in a 5 Gallon container.

The H2O ResQ is added to clean water so that it can preserve water and keep it fresh. If water has already been contaminated, then the water needs to be dumped and start the process over again.

If your questions pertains to adding “iodine” to water that you are planning to store long term utilizing the H2O ResQ water treatment, the answer is no. Of course any iodine water disinfectant treatment requires the proper concentration to be utilized. Please note, H2O ResQ is designed to store fresh, clean, municipal (tap water), or filtered water.

Iodine or bleach is typically used to disinfect water in an emergency or survival scenario and is not an effective long term method to store clean water. Also, iodine should not be utilized long term for water treatment for it is subject to side effects and can be harmful.

We also offer a better proven method to remove waterborne pathogens, such as viruses, bacteria and protozoa with a 99.9999% effective rate and it improves the taste of the water too. Our “Nano Gravity Water Filter”, Exceeds EPA and the World Health Organization's protective standards for removal of virus, bacteria and cysts.

Note soon, we will also be offering an easy to assemble gravity-fed water purification system based on our Nano Gravity Water Filter technology. The Dry Element, “Nano Gravity Water Filtration System” is made in the USA , affordable and includes everything you will need for an emergency long term water filtration situation.

Thank you for your question. There is no expiration date for the product. With that being said in order to achieve indefinite shelf life, it is recommended to store the product in a cool and dry place with the cap on.

This proprietary formula with over 15 years of testing utilizes copper/silver ion technology (as a main ingredient) at a synergistic level to inhibit Biofilm growth. The ingredients used are food grade FDA and NSF approved additives deemed safe when properly diluted. When following directions properly the PPM level of additives is below EPA and FDA approved safety guidelines.

Yes, if you are using ceramic type filters, such as the Berkey it would be a good idea, after cleaning the filter to treat it with our H2O ResQ formula to help eliminate Biofilm Bacterial Growth. Just flush some H2O ResQ teated water based on the recommended dosage per gallon through the filter prior to letting it dry out and stored for next time. Then add the recommended dosage of H2O ResQ to your long term potable / fresh water storage container.

Since you mentioned that you filter water twice a month, perhaps you might want to look at a superior filter that we also sell on Amazon that is Anti-Microbial by design, since it is silver impregnated. Silver has amazing properties and just like our H2O ResQ product, we engineered that into our Ionic Nano Ionic Gravity Water Filter as well. Our Dry Element, Nano Ionic Gravity Water Filter is based on a superior technology versus the typical Ceramic Cone type filter that Berkey and others use. You will find our Nano Filter to be easier to use, require less maintenance, out performs multiple Berkey filters and just let it dry before storing it. Ceramic water filtration systems require multiple filters, priming, constant maintenance in order to provide an adequate water supply, compared to one Dry Element, Nano Ionic Gravity Water Filter. Besides you will save money in the long run and it too is made in the USA.
