Hi, Newman,
The while buildup is almost certainly calcium precipitating out of your water--and if it's depositing on your filter to be washed away, that's a good thing!! You did well by not buying out the pool store's chemical supply. It will probably help if you will log out to the main forum page, go to the second sub-forum called "Pool chemistry for Intex-type pools" and open that up. Then read the second sticky, called "super simple pool recipe.....intex pools". That probably will answer many of your questions. Once you finish reading that, then go to the second subforum again, to the 6th sub forum listed there, called "Alkalinity and Calcium". Open that up, and read the first sticky called ""Lime softening.....". Those will go a long way toward answering the rest of your questions. And should you have any more, please feel free to post them here and we'll try to help!!
