I've read that metal staining can show up or occur after adding liquid bleach .. why, what causes this .. is it one of the by products in the bleach or is it a combination effect with other things in the pool that brings it out?
When adding liquid bleach should I use a sequestrant at the same time? Should it be added before or after adding the bleach?
Since sequestrants breakdown .. is there a sequestrant test?
