## Questions & Answers

**Q: Will it freeze**
A: There are no temperature restrictions stated on the product label, however, any liquid will freeze if you get it cold enough. If used as directed for odor control you add 2 ounces per treatment (between emptying the tank) which isn't enough to hurt anything even if it does freeze. By the way, the label states that the odor control lasts about 7 days.

I full-time in my motorhome in an area where the temperatures will remain below freezing 24/7 from about December 1 through March. I store the container inside next to an outside wall so I doubt it ever gets much below 40F. I've never had a problem the with this product or with my tanks (I drain the black tank weekly and let the gray water flow until I need to store some gray water to flush after a black water dump). During the winter I only fill my fresh water 3/4 so I have an emergency supply of water if the power fails (we're on well water). I've never had a problem with freezing tanks.

Remember, this product is advertised as odor control, not as an antifreeze for your holding tank. If you are using your RV regularly in the winter, then the biology in the tank should keep it from freezing during mild freezes. Your fresh water and gray water tanks are more likely to freeze first. If you are storing your RV for the winter, then I'd recommend that you drain all your tanks completely.

If your tanks are pretty exposed like they are in some fifth wheels and trailers, then if you are using your RV during freezing weather then you should look into a heater to keep your utility bays from freezing (a 100 watt incandescent light bulb may be all you need - I use a shop drop light when necessary).

**Q: I have a covered doggy poop container.  I'm looking for something that I can spray in, to eliminate the smell, between disposals.  Will this work?**
A: Never thought of using it that way. It didn't do a very good job in my RV 's black tank, so I started using the following product. It's a powder but I suppose you could dissolve it in water and spray it.https://www.amazon.com/Happy-Campers-Organic-Holding-Treatment/dp/B005XEFADU/ref=lp_8461597011_1_1?srs=8461597011&ie=UTF8&qid=1500353629&sr=8-1

**Q: Have outside porta potty. Does tst freezes ?**
A: NO, Gets slushy, but water will freeze

**Q: I have a covered doggy poop container. I'm looking for something that I can spray in, to eliminate the smell, between disposals. Will this work?**
A: NO, this is for an RV toilet and could be harmful to your pet, if they got into it!I would say you may want to buy a Diaper Genie
