8 gallons of Muriatic acid in ~22,000 gallon pool?

[Mr47930]

I just had my pool plastered and noticed some staining pictures below. I sent an email to the builder and they gave me 8 gallons of muriatic acid and said dump it all in with everything running on high and brush the stains. Putting that in the pool math app seems like it would drop the PH to an extraordinary low level. Does this all seem right?

Sounds like they are wanting you to do a no drain acid wash. There is alot to be careful with when it comes to that. I think they only last for a day or two then you raise the ph again to proper level. Ask your PB how long the ph should be that low.

Dont do it yourself, your pool is still under warranty! Let them do whatever they think is best. If you do it, you will be liable and warranty wont apply.

They specifically told me to do it and provided the acid.

They did tell me to come back Wednesday with a water sample. I assume they’ll have me raise it then?

Do you have a heater?

No heater.

Still, i would let them do it. I would believe they are still under contract?

I would assume. Do you have plaster or some variation of pebble tech for your pool finish? If its pebble tech, they have their own warranty people and the PB should work with them to get it fixed. If its something else i would make the PB do it. Tell them you aren't comfortable doing thos especially without express written direction on how to do it ( rate of addition, whether the pumps are on or off, duration of acid wash etc...) Technically, if they haven't turned the pool over to you, its still their pool.

We have plain white plaster. I'm going to text and let them know this isnt something i'm comfortable with.
