Salinity Drop?

What are acceptable levels that my salinity can drop between WC?
It's gone from 35 to 33 in the last 10 days. Have some salt creep around skimmer return, which I've hopefully fixed.
Need I worry about the above drop? Everything looks fine :)

.02 is not really a significant drop but am wondering is this the first drop or are you seeing this often ? Your running an ATO so you shouldn't be seeing much change. Usually it is an increase not a decrease if top is not maintained consistently . Most people experience an increase tho due to evaporation or from doaseing two part. Hm? Might want to keep track to see if this a usual reaction. Got me scratching my head for sure. Are you getting large amounts of salt build up in your stand and surrounding area? Do you have a window A/C unit near the tank ? Things to consider??? :oldman:

Ok much to consider lol. Filled ATO 5g 10 days ago. Today it's at 1g so 4g's of evap. While changing the floss in my skimmer I noticed the salt creep, prob about 5tbs worth. Also noticed skimmer's been running wet so I fixed that. And yes my AC sits about 10-15' from tank but have only ran it a couple of days (Yooper weather ya know eh) Thanks guys, I'll keep an eye on it. Was just wondering about the drop effects on live stock :)
