Walk into an indoor pool, the air is a little humid, it is warm, and there are Palm trees in large pots sitting on the deck.
All you need now is a lounge chair, a little sand between your toes and a cold Mai Tai.
A perfect looking scene with a sinister danger lurking right in front of your eyes.
The potted palms!
Like any other living organism plants need to eat, and for that most of us use standard fertilizer mixed in their water. The water then leeches out of the bottom of the pot and with the natural slope of the deck down to the pool, there is a good chance that some of the (fertilized) water will get into the pool.
Hello cloudy pool, which must be closed, due to no or super low chlorine residual!
So, what happened; basically, the phosphates and nitrogen essentially used up all the chlorine in the water, by turning the effective molecule of chlorine into a chloramine and thus requiring oxidation (chlorine) to break them down.
The simple solution is to just use fake plants and enjoy the adult beverage uninterruptedly.
