Do I have metal problems?

[sw_stupid]

That makes sense. I guess I could have them check my fill water, but I know it's metallic b/c the Vit C test. Anyway, I guess I will try and clear up the water (which now looks like a pond) first and then address my stains. Could the pool store lady be right? - change my sand every 2-3 years?. It just seems like the sand would continue to filter if you keep it backwashed.
Thanks again to the forum.

You don't need to change your sand. The only reason to change sand is if it isn't filtering - because it is gummed up. To clear your water, you will need to put in sequestering agent - more is better than not enough, keep your ph at 7.0, raise your chlorine to shock levels according to the "best guess chart", run your filter 24/7 - backwash and brush, you can also put a skimmer sock on the skimmer basket to help catch small particles - if you still have sediment in the water you may want to vacuum to waste.

As far as changing the sand...it is possible that metals have deposited on the sand as 'stain'. If they have they can redissolve in the water given the right conditions. I would inspect the sand and look for evidence of staining. If there is a lot of it I would change the sand..otherwise I wouldn't. A commercial sand cleaner might also be an option to remove the metal stain from the sand if it is present. IF the metal has stained the filter material it is a good thing...it mean that you can actually remove them from the pool easily! Ideally, you want the metals to stain the filter and not the pool for this reason.
