My cousin’s pool is plaster and there are these white dots on the bottom.

Unfortunately, he does not know his chemistry as he has a pool company managing it. Is it most probably a Calcium issue (we live in Dallas, TX)?

Thanks y’all!

Are the stains rough to the touch?

They have an interesting pattern coming out of the pop up floor returns.

Take your K-2006 test kit over for a visit and run the tests.

Post his water chemistry and then we will have something to discuss.
