ascorbic acid

Iron stains with AA treatment - what should I consider "done"? I have some iron stains in my pool. I got a filter setup for fill water that should take out ferric iron. I don't think it'll affect ferrous iron, but regardless, I want to try it out. So I'm doing an AA treatment, then will...

Hi there, I'm a new pool owner and after getting a bunch of help in the forum I am doing an ascorbic acid treatment. I have zero'ed out my chlorine with a combo of exposure and a little sodium thiosulfate. Brought pH down to 7.2 and have been following this thread. In addition, I am trying...

Hello TFPers, I recently re-finished a concrete floor with a Rust-Oleum epoxy kit and it came with two 1-lb. bags of anhydrous citric acid for etching the concrete. Do you think I could use this product in lieu of ascorbic acid for removing metal stains? If so, would 2-lbs. be enough to treat...

Hello TFPers, Can someone help me outright or point me to a guide on which Sequestering agent to use for which metal problem with respect to pool finish? I need to do an ascorbic acid treatment to get rid of some pale-brownish stains that are cropping up in my pool (confirmed not algae) and I...

I followed the process for identifying and then treating iron stains on my vinyl pool, as laid out in the TFP Forum thread here; https://www.troublefreepool.com/threads/ascorbic-treatment-to-rid-pool-of-metal-stains.2129/ as well as another detailed version of the same process on another forum...

I've had numerous above ground pools, with no problems. Our IG plaster was filled last week. The fill water looked green and the sides are now stained light brown . The builder suggests I throw in a couple of bottles of Stain Away and a bottle of Jack's Magic*. I've done enough reading to know...
