So two examples where chlorine consumption is 2-3 ppm/day, requiring a couple gallons of bleach a week. Doesn't sound bad. On the surface (no pun intended), that makes me wonder why my pool dropped 7-8 ppm today with a CYA of 30. Admittedly, I did have about 6 teenage boys in the pool for a...

Okay, so I'm gathering enough data to start to hypothesize what my real chlorine demand is. This morning, chlorine was at 14 ppm. Tonight, it's at 9. That's a drop of 5 ppm. I've also had the puck feeder wide open and a puck in each skimmer (pump running). Based on overnight scenario the other...

Understood on the whole bleach subject. I firmly believe that it is a better method; I'm just not convinced that it's easier. I went through the bleach method last year when I opened the pool and about killed myself trying to keep enough bleach around here through the process. I am likely going...

Okay, here's an update: Last 36 hours or so, I cranked up the shock level, arguably higher than I planned to. CYA level of 30-40 calls for 13-15 ppm to shock. I wasn't testing between doses yesterday and, by the time I tested last night, I was up to 21 ppm when I started overnight FC test...

Long story but I'll try to be concise. Please forgive lack of BBB method; still using traditional pool chemicals (Trichlor, cal-hypo 73%) at this point. Drained and filled my pool this spring. Within a month of opening, my pool was permananently green with bubbles in returns. Uneducated...
