Re: [Killietalk] water for hatching eggs
I don't have much experience with SA peat spawners but I do hatch a lot
of Nothos. I don't use rainwater, although I know some good breeders who
do, especially if their tap water is very hard. I hatch in the same
water I use in the tanks, but it has never been in a tank. In other
words, it is out of my storage tank, or a garbage can of identical water
I keep for such purposes, simply because it is easier to get it out of a
20 gal container than a 300 gal one. My tap water is well water that is
naturally very soft. I add minerals to it and that is what I use for
hatching. I did the same when I was in upstate NY, where the well water
had a conductivity of about 170 ppm.
Different strokes for different folks. If you are sure that the eggs are
eyed up but won't hatch, even after repeated drying and wetting, I see
no reason not to try softer water. Cutting your tap water with RO or
distilled should work OK.
Regarding the nidus required for formation of raindrops, I don't think
that would have a measurable effect on collected rain water. I think if
you measure the conductivity of clean, freshly collected rain water it
would be negligible.
