007 - Sorry to hear of the tadpoles fate, poor kids must have been upset. It would definitely be the chlorine which was the culprit. Hopefully your neighbour will have some left so that you can try again. Pond water is fine if you can obtain any. But not to worry if you can't. Presumably the tadpoles arrived with a certain amount of pond water, which of course gradually evaporates. If you do manage to get some more tadpoles, you need to get a little bottle of Tetra Aqua Safe, obtainable from most pet shops. This will take the chlorine and other nasty chemicals out of the tap water. You will need to fill a 2 gallon household plastic bucket with tap water, and then add a 5 ml teaspoon of the Aqua Safe to the water, (its blue), and stir to mix well with the water. You can then use this to top up the container with the tadpoles in. If you only need a small amount for topping up purposes, you can keep the rest in the bucket (perhaps in the garage or somewhere) until you need more. But you would need to cover the top of the bucket with something to keep any dust out. Aqua Safe is suitable for use with tropical fish and goldfish, and other water living creatures. Hope this information is of help. Cheers. Schutz. PS. I forgot to say the bucket you use must be new, rinsed out with clean cold water, and not have been used for cleaning purposes etc.
