Hobby brine shrimp hatchery

[axolotl newbie]

Has anybody got any experience with these?

I have had one set up since Thursday but nothing has happened. I used Sera premixed eggs and salt.

I have also set up a home made hatchery in a tall jug, with an air line and a light shining on it, next to a heater and using Waterlife hatchable shelless eggs. Nothing happening there either....

Well I moved my home made hatchery from a jug to an inverted cola bottle with an air line, but still no signs of life.

Surprisingly, as I was so dubious of the system, the Hobby hatchery has produced some BBS today. It hasn't kept the eggs separate unfortunately, but in hindsight I probably shouldn't have used a ready mixed pack, as it is nearly impossible to add them to just the outer ring. I will try the Waterlife shelless ones in it next time and see what happens.

How long do BBS remain small enough for week old axolotl larvae? It has taken since Thursday morning to hatch these and from the way they are wolfing them down I suspect the larvae weren't having too much luck with the baby daphnia.
