I have a whole lot of water I pump to waste from my pool sump pit and thought, why not. Took a sample to the University and it tested fine for bacteria, etc. Used it to fill my pool when it got low and it threw all my #'s off. So I tested the sump water & it tested over 1k for calcium hardness (CH). This doubled the CH in my pool, which is not an easy fix unless you drain and refill. After several months, I retested and the calcium hardness in the sump pit and it's no longer as high, actually about 1/3 of what it was. This was a brand new build when I initially did this, so I will test again next year and probably be able to use this water. I have pumped 1000's of gallons to waste out of this sump pit and it makes me sick with the price of water around here. Just making an assumption, but the new crushed rock used for surrounding the pool probably had a lot to do with this.
