Ok - HTH kit picked up, 4.25 gallons of 6% bleach in the pool as of 30 minutes ago, everything brushed down and pump and filter all on. I will test first thing in the AM and see where we are at. As far as the tab floater in the pool... should that be left floating or pulled out during this process? Double and triple checked the filter pressure and it's still operating at normal levels but will keep an eye on it.

Since my filter pressure has maintained steady and not changed so far - do I need to worry about flushing the filters during any part of this process?

Thanks again!
