Question for the water experts out there. We have a paddling pool that has been up for over a week and I want to empty it. I put a dose of chlorine in it a week ago.
so as not to waste the water, I want to transfer it into the pond which has dried up a bit recently. But will the chlorinated water be bad for the plants and bugs and newts etc?
or am I right in thinking that the chlorine will have mostly evaporated/lost its ‘zing’ by now?
“Mostly” perhaps but I wouldn’t. Watering garden etc would be better. Tap water isn’t ideal for ponds anyway (depending where you live).

My punter level understanding is that the level of chlorine already in tap water can be reduced by leaving the water to stand open to the air. I have done this (1 day or so) and nothing died in the pond. But you have gone the other way and added more chlorine. Might just take longer to stand open which you may have already done? Might need another method of dechlorination - adding a product for the purpose?
A little top up would be ok, but don't just chuck it all in. Without knowing how big the pond and paddling pool are, it's difficult to say what a "little top up" would be 🙂
Also depends what's in the pond, some things are more sensitive to water chemistry changes than others
You could use Prime or similar to dechlorinate, but personally I still wouldn't.
Some 'chlorine' tablets include other ingredients to help prevent algae etc. Anything like that is almost certainly bad for invertebrates.
I use Seachem Safe in my aquariums when adding tap water, the powder form of Seachem Prime, far better value for money a few years ago. Tiny amounts needed for my 300l tank (3/4 of provided tiny plastic spoon that came with product is maximum dose, maybe one-eight of size of a teaspoon)
But I've no idea of the chemical composition of paddling pool chlorinator.
