Hello all - this is my first post.
I just completed the "re-construction" of my pool a few weeks ago (see signature). I hate my pool builder. They did a crappy job, even the second time around, but anyway ...
Because I don't trust my builder, I took a sample of the water to my local pool store. They said I need to add calcium. The builder is telling me not to. He says that's just the pool store trying to sell me stuff I don't need.
With the finish being so new (less than 3 weeks since the resurface), I'm afraid to take control of the chemistry from the builder yet.
Is adding calcium typical? This is the 3rd pool I've owned and I've never had store tell me I need calcium before. Is it ok to do with a new finish?
