Here's a fresh culture I started, container size is just under two litres, round and low, no aeration or heater. I added a few strands of hay, a fat ramshorn, and chlorella to a 32oz plastic cup until I couldn't see through the water anymore, and about 20 adult moina appoximately a week ago, maybe ten days. I can't remember the exact day I set this one up last week but I think it was around the same time I sent out your starters. Once they had cleared the water in the cup, after approx four days, there were a noticeably larger number of moina in the cup, at that point I poured the whole thing into this approx 2l round plastic tupperware and added another 32oz of fresh water from my aquarium and more chlorella until I couldn't see through the container. This is it's current state. By tomorrow it will probably need feeding again.
