I think we have MOST of the solids cleaned out. The leaf rake doesn't bring up much anymore, we aren't finding leaves in the filter anymore, and we keep vacuuming. As we vacuum we can feel a lot of wrinkles in the liner bottom, so there is probably some stuff hiding out in the creases. I realized we only put anough cya in the water to bring the level to 10, so we will add more today. Hopefully that will help with daytime FC loss. My husband is frustrated, and just dumped 384 oz of 12.5% liquid chlorine in the pool. We will stay vigilant! The water is now a cloudy but bright light green.
