From the brand

Product Description

AQUA Water Treatment & Freshener is the most effective way to keep the "fresh" in your boat or RV drinking water. It utilizes a high-tech, water soluble formula to safely isolate and essentially deactivate chlorine and sulfur, the two most common causes of smelly, bad tasting water. Not affected by adverse temperatures; it's ideal for year-round use. For best results, use AQUA Water Treatment & Freshener every time you add water to the tank to maintain water quality and fresh taste. DIRECTIONS: Before adding fresh water to tank, add 1 fluid ounce of AQUA Water Treatment & Freshener for every 20 gallons of potable water to be treated then fill tank. Use as often as needed. NOTE: AQUA Water Treatment & Freshener is designed to keep water smelling and tasting fresh - if water has an unpleasant odor or taste, use AQUA Water Shock to restore water quality. If the odor or taste is very strong, use AQUA Water Tank & System Flush to completely clean and deodorize the entire fresh water system from the tank to fixtures to eliminate smell as well as the sludge or debris that causes it.

    Did in the egg smell from tank on my living quarter horse trailer.
    5 out of 5 stars
    Did in the egg smell from tank on my living quarter horse trailer.
    I had my living quarter horse trailer winterized by an RV service last year and tanks supposedly drained completely. After opening the trailer for the spring, filling the water tank, I took it out on the road for the day. When I walked in the living quarter I smelled a slight bad egg odor that would've had to have come from the potable water tank and up from the toilet and sink. I think driving all day, braking, accelerating, sloshed the tank around enough it exposed some possible foul odors from bacteria. I used one ounce of this treatment in the 20 gal potable water tank. As it pours you can see a slight viscosity in it, but it has no smell or aroma at all. You'll probably need a funnel, but I simply used a 35cc syringe to squirt the product down the hole. I left the trailer open to air out BTW. We just got back from a short trip out of state, and the living quarter has lost that odor smell and it has not returned. This bottle will go a long way for us since we only have the 20 gal tank. I never drink the water, but nice to know if no other choice I'm going to be a heck of a lot safer than before!

      We love this stuff. We didn’t have it for the fresh water tank in the camper one time, and we knew it!!! With it, zero odor. Haven’t gotten sick from it. Doesn’t change the taste of the water. Must have for camping.
