I'm inspired and could use some re-assuring.

I have a simmilar situation. First the background:

18x48 round entex(blow-up ring), Cartridge Filter.
Metal in the water (got that under control through CL/PH maintenance-PoolMagnet-and AA)
Water was great, went away, Major Rainstorms,
White Cloudy water (can see bottom but it is very Hazy)
PH - 7.2
TH - 200
TA - 80-125
FC - was about 1-2

Based on some site posts, I was encouraged to shock. I used powder Sock-it in small amount and gradually brought my FC to 10(+) and have maintained overnight. FC levels did not drop as I would have expected if I was fighting something like this post describes. The FC level just maintained itself. The water has not gotten any better or any worse - its just the same cloudy/hazy water.

I have one additional abnormalty - The pool filter has a Fountain on the return. The bubbles that are created from the splashing water appear to linger longer then it should. If I pop a bubble, I see a circle of white residue.

I could use some support and/or advise because I'm losing my POP!
