I started my slam yesterday. Pool Math and nice people said I needed to get my chlorine up to 16 for my pool. I started with 4 gallons @6% according to Pool Math.
My FC was at 10.5. I added another gal. at 3:30 and at 4:30, FC was 13.0 I added another gal at 5:15 Tested at 6:00 and FC was still 13.0 I added 2 gallons at 6:45 Added 1 more gal at 7:30. Tested at 8:35 and FC was 19.0, so I over-chlorinated by 3. I did the over night chlorine loss test and at 6:15 a.m. it tested 17.5, a loss of 1.5. At 7 a.m. today I added another gallon. At 8:30, FC tested 18.5. At 10:30 I received an emergency call that I needed to pick up my Grands, over an hour away. So I poured in another gal. and left. At 1:25, I was back home and tested. So about 3 hours later ,the FC was 10.5 again! I poured in 2 more gals. and at 2:15 added 2 more gallons. So 15 gallons so far! Since letting the FC drop to 10.5, did I totally mess up? My pool is beautiful. Very clear! I still have seen no signs of algae. I have blisters from brushing plus I have my robot in. I backwashed once. My pressure had gone to 15. It is staying on 15 instead of the normal 11. Something is definitely wrong though! Where is that algae? Just took another FC at 3:00 and now it's 18.5. So 2.5 above my target.
