Thanks for the reply. I will wait.

The manufacturer did say it was calcium that fell out of solution due to high ph. I just read on the blog of a "dealer of our brand pool" that the manufacturer sent out a "technical release to their dealers regarding this issue"! I will also definitely call the manufacturer again and ask for a technician to come personally and provide steps for treatment that will not void my warranty. (I may call that dealer first and see what info I can gather from them.) We are not comfortable scrubbing everything. The surface already seems to have lost its shine. (FYI: The manufacturer actually performed and paid for the first acid wash treatment.)

I am aware that I cannot use specific names on your blog. (I will gladly email or message you any specific details if that helps.)

Here is some of the info that I found about the "technical release from the manufacturer" that seems to explain why the whiteness I have seems to be a part of the pool (smooth)...here goes: "If the problem is more severe, or the pool has been left with a high PH level for an extended time, the calcium deposits will combine with the chlorine in the pool and create a salt called Calcium Chloride. The salt will attach itself to the pool surfaces and cause areas of the gelcoat to look white. There are two stages of this advanced calcium chloride. The first, and easier to treat, stage is less advanced. If the gelcoat returns to normal when it’s hydrated (or just wet), then you can treat it using the same chemical solution as the less sever case mentioned above. However, it will take up to 6 months for the treatment to totally dissolve the calcium chloride. Due to the time this takes, and the fact that the water will be very acidic in this time, we recommend that this treatment be done in the off season. If, perchance, the salt deposits are visible even when they’re hydrated, the treatment is not as easy. An effective chemical treatment hasn’t been found or developed so the recommended solution is to remove the salt is to buff and polish the surface to return it to its previous condition."
....BUT the confusing for me is.... it says: ...CaCl will form if the problem is more severe??? I never had noticeable or rough calcium scaling stuck to the pool...(it started off white and smooth) ....so to me ... deposits must have still been suspended in order to combine with the chlorine to produce CaCl and then attach itself to the pool surface??? SOOO Confusing!.......

Thanks for your time. I am impressed with your site. I am very interested in using your no nonsense pool water maintenance program. I'll need help with that.

I will wait for your response. (There are SO many different solutions/remediations out there; it is scary!)
