copedpods

Copepods or something else? Quite a large and dense population. I’ve seen copepods before but never this big. I have some on my glass which are very small.

Hi all, Curious if anyone has any experience culturing their own copepods? My question is, how do you control nitrates & ammonia from copepod waste? Is a bi-weekly harvesting/water change enough to replenish & keep the colony alive? Any/all advice & experience welcome! Thanks in advance :)
