So my calcium has always been a bit low and I have just managed CSI by letting the pH be a bit on the high end of 7.8 or so.
With the new PoolMath update, it kept telling me my calcium was low (200) so when I was at Lowes this weekend I picked up a bag of calcium hardness increaser. It was made by Clorox, which I have read bad things about some of their pool products, but that was my only choice and I thought calcium was calcium.
I put half the 5lb bag in the deep end and brushed a bit, seemed pretty easy. This morning there are several rusty spots by the drain. WTH. I brushed again and that didnt seem to work so I have the robot working now. The spots are small and look like a handful of the granuals rusted, similar to what iron fertilizer pellets do to your sidewalk.
Has anyone run into this and have thoughts on what I should do? Until then, I'm avoiding all Clorox products, especially for the pool %*#$#&$!
