Started my first copepod cx 7 days ago with a combination of Tisbe/Tigriopus/Apocyclops pods from "Florida Reef". Water is tinted with Nannochloropsis phyto. Do I need to be concerned with ammonia? How long before I need to perform maintenance and can I just add more SW to my jar or do I need to filter out pods and use all fresh water? Any advice would be greatly appreciated and thanks!
