This is the same Potable Aqua we have been selling for 10 years. However due to FDA regulations we can no longer sell the bulk form of this product UNLESS it is being put in kits. If you want to purchase the WA33 Bulk for kits you are building you will be asked to sign a release form (one time) and we will keep it on file. Product Details: – Iodine based (no chlorine) – 2 tablets per 1 quart of water – Ready to use in 30 minutes – Makes 25 quarts.
