Any kind of table salt (no MSG or other non-NaCl flavor substances).

We’ve used brown rock salts in Thailand and flakey salts from fancy restaurants. It all works. However, larger grained salt may require the user to mix more salt into the salt brine bottle. This is also true for rock salt.

Some salts have preservative agents that take up space. These also may require more salt mixed into the salt brine bottle, than the instructions recommend.

Simply remember: If you get a low salt light, just add more salt!
Any water that you’re planning to drink after treatment. Start with the clearest water possible, and avoid extremely murky or sludgy water.
Any 12 volt battery over 7 amp-hours. These are typically motorcycle or car batteries and range from 7 amp-hours to 80 amp-hours (though you can find them even bigger).

Don’t forget to buy a charger at the time that you buy the battery. Ask the store owner which charger to use with your battery.
A 7.5 amp fuse.
Yes. You can purchase a power supply.
Use the chlorine test strips provided. The SE200 kit comes with 10 chlorine test strips that will help you determine if the water has a safe chlorine residual. You can use any chlorine test strips that test in a range from 0-5ppm. The target concentration range is 0.2 to 2 ppm, 30 minutes after treating water.
You can use any pool chlorine test strips on the market that test a range of 0-5ppm.
Yes, it comes with a one year limited warranty that protects against manufacturer defects. If something is not working properly, MSR Global Health wants to hear about it.
First, check the troubling-shooting options for common issues. You may just need to charge your battery, or add more salt (the two most common problems).

If your device still isn’t working, and you suspect it’s a manufacturer’s defect, please email global.health@cascadedesigns.com or call 1-800-531-9531. Whatever the issue is, our customer service department will help you figure out what is wrong and what to do about it.
Backcountry Dog Etiquette

During a recent ski tour to Table Mountain in the Mount Baker backcountry, three friends and I rescued a lost dog. It was an hour before sunset on a cold December afternoon and there were no other people in sight when we spotted the shorthaired mutt searching for her owners. As the shivering, disoriented animal limped higher up the mountain, away from the parking lot, it became clear that something was wrong. One member of our group, Kirsten, attracted the timid dog with an avocado sandwich. Kirsten phoned the number we found on the dog’s identification tags and was able to get in touch with the owner, who was waiting in the cozy Heather Meadows lodge, about a 30-minute hike from our location. The dog was not able to run…
