Another great looking tank, hope the tetras appreciate it when it is cycled! You are using the same filters as I am, don't forget you can remove the base so there is more exposed sponge area, and it makes cleaning the sponge easier as you don't need to pull the body apart, just pull it out from the bottom etc, you don't even need to remove it from the tank side, just rotate it 120 degrees!
You did well to save even some of the eggs to shrimplets. I wouldn't expect you to see them for a while in the tank as they hide a lot for the first few weeks or more. As when I transferred to the new tank there were loads of newborns I didn't even know were in the old tank?????
I saw this at the weekend which may interest you, I know you made your own but there may be a tip or 2 to help if it happens again:

I finally bit the bullet and started culling again, did 10 juveniles, tank still looks over-run though! Got to do the shrimp tank weekly maintenance today.
