6 year old Pool with Brown and Blue Stains on Sun deck.

[GHG7F0]

My pool is 6 years old and water looks great. On the steps I see brown staining. I rubbed a tab and it’s now very white maybe to white. Hope I didn’t rub off a surface coating or something.

I also have blue staining on the steps and I’m not sure if it’s staining or maybe a blue tint was put into the plaster and it’s coming off. I ordered a stain ID kit from Jack Magic. I did have a Pool RX for the last 2 years so maybe copper or like I said maybe it’s a blue tint wearing out. Any ideas?

Probably copper and silver.

PoolRx+ contains a proprietary blend of minerals that continuously and effectively eliminate algae for up to 6 months. These minerals immediately dissolve out of the cylinder and form a stable residual throughout the whole body of water. During the pool’s filtration process the minerals are rejuvenated every time they return and pass through the cylinder.

Active Ingredients:
Copper Sulphate Pentahydrate: 86.85%
Zinc Sulfate Monohydrate: 1.51%
Silver Nitrate: 0.40%
Other Ingredients: 11.24%

Yes, this is what I was thinking.

I communicated with a pool professional and he said the blue plaster was tinted and this is mottling. Eventually it will get resurfaced so I’ll live with it for now. Thx

Tinted with copper stains.

Mottled with silver stains.

Can you pull your filter cartridge and show it before cleaning?

Try putting vitamin C on a spot to see if anything happens.

I was able to remove the brown stain on the small step that was from tabs from the dispenser (not in pic) with vitamin c but it didn’t help the stains in the picture. I have a person coming tomorrow to test it. He thinks it’s copper but we will see tomorrow. He is suggesting an acid wash. I think I might try Jack Magic first. Thx
