Please help me. I thought I could finally handle one problem on my own, but obviously not! My water was very cloudy (couldn’t see drain at 8’) with a green tint. There are deposits on the “slopes” of the walls (where it angles down toward the bottom) and on the flat surface of the shallow end. They look like dirt but dissolve anytime you get near them. It seems to be mainly where the jets spray. My filter hasn’t been off in 3 weeks. I have maintained 15ppm FC for a week now. The green is gone, but it is still hazy. I can see the drain, but it isn’t crystal clear as in years past. I brought it up to 15ppm with bleach and my SWG has been holding it there for the past 3 days. EVERY morning the “sediment” is there again in the EXACT same spots. I vacuumed and backwashed 3 days in a row last week – seemed to help a minute amount. I have pantyhose in the skimmers and I have tried clarifiers. I am not building any backpressure on the pump. A lot of this sediment came in a few weeks ago when I added fill water and didn’t know the water company had just fixed a broken pipe. We had a lot of sediment in the toilets in the house and I added water to the pool for hours Also, I am adding about 32oz. of acid a day to keep the pH around 7.2. I assume it is because my SWG is at 50% and running all day. Questions:

Are my pH readings likely to be off at this FC level?
Why the haze? Algae? Calcium? Sediment?
How do I get this stuff off the bottom of the pool and keep it off?
I know there are metals in the water, but do they cloud it? (I thought they just stained)(it has a bottle of sequestering agent in it)
Vitals:
FC: 15
CC: 0
pH: 7.2
ALK and CAL: 90, 120 (don’t remember which is which)
CYA: about 50
I am going to wait until I get this haze cleared up before I fight the metals. I don't want to fight too many battles at once - I can't even win this one.

I am really ready to turn the pump off, but I know I can’t until I have clear water. My electric meter will be needing new bearings before long!!!
