Hi all, I've been managing my pool since June using BBB, and I have not had any problems.
This morning when i went out to do my daily levels check I noticed a couple markings on the pool that looks like rust. They are small in size, about the size of a dime. They don't brush off, and its smooth to the touch. I have maintained levels and everything has been good.
This Mornings Readings:
PH 8.0 (lowering this back to 7.5 as we speak)
CSI(using pool calculator) is .38
PH rose a little high yesterday from rain I think, but its back down now.
If I plug in numbers for my PH being high CSI it rose up alittle above the .6, but it was short.
Is this Calcium scaling? Is the best ways to remove is just a pumis stone?
