First Timer Ready to Fill, Could use some help

[jkoch]

Thanks, I'll get more CYA. Can I just dump it into my skimmer? I have a sand filter.
Also, Should I leave cover on or off?

Yes, you can dump it in the skimmer. Just don't backwash for a week to give it plenty of time to dissolve. I usually run my pump 24/7 for the first couple of days after I put cya in the skimmer. I don't think it matters one way or another about the cover.
