Can't figure out stain

[Dr.Ron]

I sprinkled in 8lbs of ascorbic acid. It doesn't seem to have worked. I ordered another 8lb bucket but this time I will place the aa in socks with rocks directly onto the stain several times with hopes that the direct contact will remove it this time, same as my test spot did.

I'll report back. If that doesn't work the I give up! Overall this summer the stains are at least 60% lighter from time and the metal removing treatments anyway.

Did you eliminate the chlorine from the pool prior to adding the AA?
Did you read Ascorbic Acid Treatment - Further Reading

Honestly, no and no.

So the bulk of the AA was consumed eliminating the chlorine.

Apparently. I have the aa coming tomorrow. Ph is down to 6.9 and chlorine is less than 1. I'm ready this time. Would you recommend I throw it in on the stain again or try the sock method?

If the stain is localized, use the AA in a thin sock.

Be careful of your pooling getting algae.

It's on the sundeck..a few areas. I'll try sprinkling an area 1st since now the ph and chlorine are where they need to be. If that doesn't work then I'll just keep doing the sock thing.
