scale

[mick shea]

I use Baquacil and have a 20 year old inground pool 16 X 32
right now I have scale on walls and floor in deep end.
I have reduced the PH and brush pool 2 to 4 times a day
for the last three days but not having much success getting
rid of scale. Is there a Baquacil product that I can add to
water that will help me in my endeavor ???
