Huge leaf stain after Hurricane Irma

[southflorida427]

Got back home after leaving for a week because of hurricane Irma. Although water was blue, it was full of leafs. There was a huge pile of them by the deep end drain cover.
After removing all the leafs there is a huge stain under where that big pile was.
Last night I added a jug (2.5 Gal 10%) liquid chlorine for the moment as I prepare for SLAM. I can see the stain getting better, but it is still bad.
Tomorrow I will run all the tests and start SLAM. I'll follow up with results.
Besides SLAM, what else I need to do to remove the stain?
Thank you!

The organic stains should be removed by the chlorine. I think the SLAM (and brushing) should greatly remove the problem.

These are my test results:

1) CYA guesstimated at 25. At the 30mark the dot was slightly visible. It is OK to add some pucks and slowly up it up to 30-40? How many pucks (13k gallon pool)

2) CC is low (almost non existent). Should I perform SLAM?

3) See stain on pictures.

Thnx for the help!

Using pucks to raise CYA and FC is fine. Use PoolMath to calculate it. At the bottom of PoolMath is Effects of Adding Chems that will tell you how much CYA and FC each puck will add. A SLAM isnt needed for CCs but higher FC level will help to remove the stains faster. More here, Pool School - Pool Stains

had the same leaf staining, it's slowly fading hoping a FC of 5, CC 0.5, CYA 70 will work. I'm still losing 1.5-2.0 overnight but don't want to SLAM it if I don't have to. Good luck.

How do you chlorinate? If you do not have a SWG, then a FC of 5 is too low for a CYA of 70ppm.

I filled out the signature in my profile don't know why it's not displaying in my response. SWG does most of the chlorinating, I add bleach if it gets behind.

That's it, somehow the mobile version isn't displaying my signature.

Just to update on results: stain faded away completely. It was just a matter of time and proper chemistry. Thank you!
