Local club states 12% chlorine in the lap pool. Does this seem high? Are the general pools where the kids are a little higher (or lower)?
12% would melt your eyes and lungs as soon as you walked in the door. 12 ppm is probably what they’re talking about, but that’s still pretty high. 5 ppm is probably about normal for a pool kept at “workout” temperatures (mid to high 70s). The warmer the water, the more chlorine they tend to use. A pool kept at 84 (very warm…terrible for training, anyway) might need 10 ppm.
How did they measure the 12%? Not gonna wanna be near 12% Cl in water. Is that 12% or 1.2 ppm? It that Free or Total Cl.
1.5 -3.0 ppm. Okay from 1.0 to maybe 5.0. Best levels around 1.5 - 2ppm for Cl with ph of 7.5.
If you are using the tablets and often used pH testing kit, it is going to be hard to get a reading of 12ppm.
12 ppm is probably going to bleach the your swim wear.
Maybe it was 1.2. I would say a typical pool is from 1.0 to 2.0.
Don’t forget the decimal.
I used to manage all the pool chemicals in a water park. One night someone left the chlorine pump on to the slide catch pool.
The next day I guess the morning pool guy didn’t notice it and kids were coming down screaming “Mom it burns! It hurts so much! waaaa!” I was a lifeguard that day so i got to watch the whole thing.
We tested chlorine via tablets in viles then compared the color to a chart. I think our chart only went up to 5 ppm. I tried to keep it somewhere between 1.0-3.0 ppm. I think if it were at 12ppm that would be some serious health issues. That effects the PH balance which can mess you up too. I don’t remember what pushes what.
The only time we would get the pool to a really high chlorine level would be to “shock” the pool if some kid had diarrhea. We would get everyone out and pump in a ton of chlorine. Over the radio we would use the code “10-30 Brown Wet” for diarrhea. There were also 10-30 Red, 10-30 Yellow, and 10-30 green codes :).
I don’t know the language of pool talk. I asked the kid (I am old) on the phone to talk to me like I was two years old. How much Chlorine is in the pool. He said we keep it at 12% Chlorine. I repeated what he said and he confirmed. So, I take it he doesn’t know what the hell he is talking about. This is a huge company. I will contact corporate and ask them. The water does seem a bit rough.
Used to run a pool. 1.5ppm (parts per million) was the target. We tested every 2 hours, any readings over 5ppm meant closing the pool.
