Brown Pool Water...please help

[AndyGuthridge]

Thanks for the warm welcome everyone!
Ok...I have a drop test kit that only tests CL & PH and todays numbers are:

CL - 3.0+
PH - 6.8

I have noticed that the since I shocked it the water has changed from brown to gray/green but I still cant see to the bottom. I have a Hayward sand filter and the pressure is right where it should be. Again, friends suggested to just keep shocking since the brown changed to green and thats great if that's all it is. Plus I've added a scum sock to the skimmer to catch all the stuff that may be making its way back through the filter. Since the CL is high I'm pretty sure I'm safe for now as far as algae goes. If I need a sequestering agent, can I add it since I've already shocked the pool...I've heard that can make things worse. I plan to have my water tested tomorrow for metals. Thanks again for the help and walking this "newbie" through this mess.
Andy

The brown may have turned to green because the high chlorine levels caused the metals in your water to drop out and stain your pool. You can tell if that's happened by lowering your pool just a bit and see if the walls appear yellowish. I would go to the metal stains forum and read everything you can there, especially anything posted by Marie (mbar, who is our resident expert on metals, second only to Ben!). She's got lots of first hand experience in metal control.
