Hey there. I have A 18,000 gallon fiberglass pool. I have some staining that I have determined to be iron staining. A test of ascorbic acid lifted the stains. I have purchased 4 lbs of citric acid and a bad of jack’s magic the filter fiber stuff.
It has taken me a long time to get my chlorine down. It is now down to 2.5 so I am anticipating performing my acid treatment in the next few days.
I have a sand filter and my main questions are about the filter. At what point do I add The Filter Fiber stuff and what do i need to do to protect my filter from the acid or metals?
I’m not sure the order I put my pump on recirculate vs the regular setting vs backwash.
I’m new to this!! Eek
