new plaster

[deepnnet]

Thank you for your responce. sorry for taking so long to reply,I've been
really busy the last couple of days.
Let me make the question more clear.
How soon after a new white plaster pool is filled (fill water @ 50ppm)
should calcium be adjusted? If left unchecked , the calcium will rise on
it's own during the 4-6 week curing process.(I've seen it go as high as 300)
Note: I do keep the pH low ~7.0 during this time to battle the rising
alkalinity.
Should I add calcium right after fill? will that halt further calcium release
from the new plaster? Or is the plaster going to release more calium anyway (low pH)
and possibly end up with very high levels at the end of the curing process
and possible scaling problems?
Thank you very much! Rick aka deepnnet
