If your pond isn't too big you could take out some of the weed a bit at a time and put it in a bowl of water and gently remove the baby newts to another bowl and put them back when you've done.
If they still have external gills (feathery bits sticking out) they need to be in water to live. Keep a watch out for other desirables as well, dragonfly larvae etc,
Looks like we all missed Chrissie's question, sorry Chrissie. Water is never pure, there are all sorts of things in it. A fountain stirs it all up and mixes in air and it all froths up.
