Okay, so I kept chlorine going all winter, but honestly didn't keep the pool balanced otherwise. ?
So, I noticed that the steps were beginning to turn brown. My chlorine had been a tad low, so I shocked the pool. Nothing changed, if anything, it spread. I took a water sample to the pool folks and they said I had no iron or copper. They had me balance everything, but drop chlorine level, then do ascorbic acid treatment.
I used 2 lbs and it lifted some and just streaked in other areas. I let the pump run for 2 days, back washed quickly, then added more AA. The pool is now the cleanest and clearest that it's ever been. Okay, so the pool folks told me that, since it wasn't metals, I shouldn't use a sequestering agent. I tested tonight and chlorine is 0, pH is 7.2 and TA is actually a bit high, at 1100. I began increasing my chlorine slowly, as told, which is my chlorinator set at 3.
Here's my concern. Although I was told no sequestering agent, everything here says that I should be using one. I am afraid of the stains coming back and don't want to mess this up. I also see a clear film, in my skimmer. I assume it's from the AA, but have never seen it before. What is it and what should I do from here?
Any help would be greatly appreciated!

Well, you're correct about needing sequestrant IF you have metals. One problem is the pool store's testing can be inconsistent at best, however metal testing is one we often have you go there for. But if you took a sample from your pool water, it may have given a bad results as the metal had already precipitated from the chlorine. I would suggest having the metal tested from the source .... right from where you get the water (garden hose, etc). That may provide a different reading.
