Good morning, I purchased ecopods by AlgaeBarn late last night and was wondering if you can crash your tank adding too many copepods in the tank? It's a 20 gallon high tank. No corals. Tank is 5.5 months old and looks to be starting its ugly phase. I'm working on getting 5 gallon refugium started as well. Can you put these in the fridge like you can tigger pods by Reef Nutrition if I don't put them all in both tanks? I know to dose phytoplankton daily which I did after I added tigger pods on Thursday and they disappeared within two days. Do copepods need a filter or aeriation in general for culturing? Or would an air stone be good?
