[quote=”Peter Finke” post=1780]The simplest way seems to me to use pure rain water. Again I repeat that all people whom I know that they are working on this base have no problems with breeding our fish. Among them are the best Paro-breeders I know. Some even maintain that pure rain water is better than anything else. [/quote]
Do you mean they really use only rain water – without adding any acids (except perhaps peat fibres or something like that). That they take the pH as it is? (Even if it is, as in my case, about 6,0 – never more)?
