Complicated cycling question

you are in a bind. You did good by keeping the majority of the lr alive, but as already mentioned, the bacteria population has declined because of lack of "food." Taking into account these circumstances, I would go out and get some easy corals as you said, some zoas, a mushroom or leather of some sort. I wouldn't get that may fish at one time though. I would get one or two small fish such as a clown or damsel of some sort, anything more and you would be risking a new cycle too much. This position your in sucks!

 

Amen!
