It looks like I am going to do a no drain acid wash to clear up some stains. I'm going to add between 4 and 6 gallons of muratic, brush for a few days, and then counter the acid with soda ash. Pool calculator says I'm going to need more than a 1000 oz of soda ash, so I doubt I'll be adding that much.
Anyway, what happens to the soda ash? Is it nuetralized forever? Does it change any other parameters? Will it change the feel of the water?
