I needed to clean out my "pool bucket" that I use for storing small toys in after they dry as well as for bucket tests when needed ot just mostly for science.
Well, I let it sit outside and get all nasty with the bad weather, got some leaves in the bottom and the rain water that collected became rather gross!!
So I rinsed it out, meh... not clean enough I decided.
So I put about an inch or 2 of tap water in this 5 gallon bucket, put less than a splash of bleach in there and let her sit for about a week.
All the staining from the tannin of the leaves went bye bye and it smelled fantastic and fresh bleachy smelling. But not too strong.
So I went and got a white washcloth that had been used for dishes, sitting on the drain board. It looked and smelled clean, so I didn't bother rinsing it.
I proceeded to wipe the bucket down, inside and out with the remaining bleach solution. WHOAAAA!! Can you say chloramine smell?? WOW!!
Reminded me of a public swimming pool.
So I was very curious and decided to test this now white cloudy water.
Did an OTO test to verify that it wasn't out of range of the FAS-DPD test. I got a medium dark orange. So I proceeded with the FAS-DPD test, knowing it'd be high.
Boy oh boy! Had to use 2 scoops and took 95 drops, the 96th had no effect. Picked it up and held it to the kitchen light in front of a the white wall as a background. Nope, no pink, just muddy brown water.
So I set it back down on the SS and spun her some more, turned a bit pink. So I added 2 more drops, 3rd did nothing. So I repeated this once more and still had to add 2 more drops to remove the pink.
That gives me a ppm of 49.5 FC. The water is now a somewhat muddy brown, and still cloudy. No longer white and cloudy, but dirty, like earthen dirt.
Then I did the CC test.
Turned pink within 1 drop. HAHA
Finished adding the 5 total needed drops, then proceeded to titrate that to clear.
I got a CC reading of 21.5ppm. OUCH!!!
That's A LOT OF CCs!!!
Goes to show how much is in a public pool, that STENCH in the air. Just like what I smelled in that bucket.
That rag must have been nasty dirty!! Just because it looks clean and smells pretty clean. Doesn't mean it is. YIKES!!
Well, that's it. Just thought I'd report on my fun experiment. Didn't want to blow that much reagent, but it was fun. In the name of science and curiosity.
