Is it dangerous to add chlorine to a small pool (still) no filter connected, while children are swimming in the pool, I was present when this happened with the adult there stating that they mix the chlorine up with their movement (it seemed to to a christalized chlorine which he grabbed a handful and threw it in)this caused me concern, but as I have no experience with pools I would like to know if this is dangerous.

Answer:

This is certainly not recommended and can be dangerous, especially considering there is no measuring going on there. You can add chlorine to a small pool like this, but it should be pre-dissolved, thoroughly mixed and ideally in the 1 to 4 or 5 ppm range before kids get in the water. Excessive chlorine levels can cause skin irritation, perhaps burns and the off-gas may even cause breathing difficulties. This is why chlorine is never added (even in very large pools) when swimmers are present in the water.
