I'm on day 4 of my first slam after the pool store had me put everything imaginable in, making it worse and worse. Before beginning Slam my levels were :
Before this, I had drained and refilled half the water to lower CYA and adjusted pH down from over 8.
I've added to maintain FC at 12 four times per day. I have brushed everyday. Sides are not brushing easily like I have experienced before. They seem stained?? I have back washed everyday (even though pressure hasn't changed at all, it is dirty). This morning, I only lost two ppm FC. It is still really not visibly better at all and I'm concerned I'm missing something. It is murky, greenish brown. You can barely tell brushing is doing anything.
