We are trying to get ready for the 4th. I have been slamming my pool for a week. Yesterday when it was time to vacuum, I got started and all to late realized my sand filter was blowing all the alge right back into my pool. We deep Cleaned the sand filter, and as of this am my ph is great, But I have zero chlorine. Can I shock it this am..(we always shock at night) and then vacuum again tomorrow? Thanks for the info!!
