I am draining my pool to upgrade all the plumbing to PVC (it is copper now and has air leaks).
The guys suggested an acid wash to clean the scale deposits on the plaster.
I hesitate doing this as i did not do any research on that, is this a good idea to do the acid wash?
I do have a lot of scale on my walls but i am concerned that the acid wash will harm the plaster.
18000 gallons in ground
CH800 (will go down to normal level after refilling)
Calculated ICS: 0.6
Also they are talking about doing a conditioner of the water when they refill the pool, what is that?
