Dry Salt & Moisture

[droidus]

I am watching this video from BRS TV: https://www.bulkreefsupply.com/content/post/faq-41-does-aquarium-salt-ever-go-bad. I also got clumps of salt in an air-tight food container. I am not sure why that happened, but anyways, he says that it is not good when it clumps up like that. Do minerals start to decompose, or break down when clumps start forming? What is not good about it?

Somehow moisture got into your container. I'd look at getting a better container. I would use the salt without hesitation but if this is a reef tank go ahead and test the new saltwater to make sure the Cal and Alk are still within range

I had one of these lying around, so I used it: .
Could it build up over time, with just opening/closing it when going for more salt?
Referring to Instant Ocean's site, I see Cal listed, but not the Alk value; what should it be?

Moisture, be it from the ambient humidity in a room/house or droplets of water can cause the elements to defuse and chemically react. Thus the clumping.

Does your salt come in a resealable bag? I keep mine in the bag and put the bag into a sealed container

It did not.

I keep my opened salt mix in a 5 gallon bucket with a lid that seals it. If i get a box of salt, i open one bag and empty it into the bucket.

Stays nice and dry.

I leave mine in the bag with a clip so its definitely not sealed and I get clumps sometimes. As long as it doesnt get wet it's fine.
