Re: [Killietalk] Problem hatching brine shrimp eggs

[George & Melanie <caraway at erienet_net>]

I would suspect your water quality. That is the water you are using to 
make up your hatching solution. From personal experience I have used 
hard water and soft water from a softener when making up a hatching 
solution. I often found that my water changed enough to often effect the 
hatching rate of the brine shrimp eggs. Now I only use the water after 
my softener and it seems to stay pretty constant and I get uniform 
hatches. I would suggest you check your water sorce to see if there has 
been any significant changes.
