Weekly update... Sadly I will have to claim this round as a complete failure. Every now and then at night when I look in the tank with a flashlight I can see one, maybe 2 small amphipods but other than that I'm seeing this as a total loss. I do still have some copepods on the glass here and there so the water must not be too bad. I ordered another starter culture of Amphipods tonight so next week we'll reset the whole thing and see how it goes.
