big problem with iron stains

I see you posted in the polyfill thread- its quite old so I’ll answer your question here.
Polyfill is what is used to stuff cheap pillows & stuffed animals.
It’s in the craft section at most stores.
In the US its about $5 a bag. Or you can recycle some from an old pillowIMG_7157.jpegIMG_7158.jpegIMG_7159.jpeg
 
You can normally find Polyfill ( it is used to fill pillows) at places like sewing stores, general stores, etc. In the US, we find it at Walmart, hobby stores, etc.

inserting this material in the skimmers should it absorb the oxidized iron? should it change color once the iron is absorbed?
 
If the water is changing color when chlorine is added try the polyfill method to remove as much iron as possible before adding any more sequestrant - afterwards deal with the stains using the aa treatment & sequestrant.
The sequestrant can only do so much if your iron level is very high.
today I added 6kg of sodium bicarbonate but the ph didn't rise, why do you think?

Because your ta is incredibly low?
Can you confirm that this is the size of your pool? & add that to your signature.
250 cubic meters is around 66,000 gallons
Here’s the effect on your ta from that addition.
What is your current TA?

Those are filter balls they go in your filter in place of sand. We don’t recommend using anything but sand in a sand filter.
This is what you need. You just put some in the skimmer👇

yes I know they are filter balls for filters but I didn't think of putting them in the filter but in the skimmer

They are very expensive & i am not sure exactly what they are made of or how many might actually fit in your skimmer.
If you have an old pillow at home you can cut open just use that. Most cheap pillows are filled with it. The longer you wait to remove the iron the more staining you will likely incur.
 
si lo so che sono palline filtranti per filtri ma non pensavo di metterle nel filtro ma nello schiumatoio
Ho comprato questo che mi avete consigliato e ne metto un po' in ogni skimmer (ne ho 5 in tutto) ora il materiale dovrebbe cambiare colore se assorbe il ferro o no?

Translation:
“I bought this one that you recommended and I put some in each skimmer (I have 5 in all) now should the material change color if it absorbs the iron or not?”
Reply:
It should turn brown if it absorbs any iron - when it gets dirty you can carefully remove it and rinse it (outside of the pool somewhere ) & then put it back in the skimmer to collect more iron

Rispondere:
Dovrebbe diventare marrone se assorbe il ferro - quando si sporca puoi rimuoverlo con cura e sciacquarlo (fuori dalla piscina da qualche parte) e poi rimetterlo nello skimmer per raccogliere più ferro
Lo indosso da due giorni ma finora non ha cambiato colore
