Pool got noticeably clearer today. Still not where I want it, but notably better. I'm pretty encouraged.

I lost a good 3-4 ppm of FC again over the last day. I'm going to keep the FC up at 15 for another couple of days.

I think that DE was a really good tip. So, everytime I backwash I put in more DE?

Thanks for the tips, this is as good as the pool has been yet this year.
