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
