pool is covered so to add acid must raise the corner of the cover but it then sags and some of the cover is in the water
acid is 31% acid and is diluted 1pt in 3gal or 1pt in 25pts
1/25*31 is 1.2% acid
now 1.2% becomes way less as soon as it hits the pool but...
is there any way this could hurt the cover?
