Just joined! We are newbies with a new home with existing AG 18' pool. This spring has proven to be challenging trying to keep the pool clean. We opened it, no algae, just pollen from the terrible cover that eeekked through winter. The next day Grackles completely turned my pool into their toilet. We threw in 4 lg bottles of Clorox and 3 3" tabs into skimmer. The water immediately clouded. My husband put in clarifier as I vacuumed out the pool. we had a new cartridge too. After a day, the pool cleared, but the stinking birds keep dropping their poop into the pool!!! Any suggestions on how to stop them? Will I need to do more to keep pool sanitized for kids to go in?
