Hi, So, I’m nearing the end of my slam and have let myself run out of the 0870-I DPD powder. Should have some tomorrow sometime. I’m thinking for today and tomorrow til I get the DPD powder, I would use the readings I got yesterday when I ckd the water and add chlorine accordingly. My thinking is this would be better than not adding any Chlorine at all. Am I even close to being ok. I’m attaching a pic of the pool this morning. My reading at 5:30 this am was 9.5 and I’m slamming at 12. Any thoughts???
