Open salt bucket storage comments ?

[gregzz4]

I know it's late but I had to get busy
So, when everyone is awake and reading ...

I had to open the bucket before I thought I would ( thought I had enough left in a bag )

I know that pouring salt causes moisture/salt to build up on whatever measuring container is used, so ...
I used a clean, dry measuring cup to scoop the salt from the bucket and poured it into another cup. Then I poured it into the water

For now, I placed a garbage bag inside the bucket to cover the top layer ( ) and I put the lid back on tight

Beyond this, what are the tips please to keep the bucket from turning into a rock ?

I estimate it will take me 4 months to use a 160g bucket with 10% weekly or 20% bi-weekly changes
In one year, 3 x 39.95 vs 13 x 14.95 is a $75 difference, so I'd appreciate your help to keep buckets dry
