Make sure you place your container away from areas where they may experience extreme temperatures such as near a radiator or in a cold utility room or garage.
In the first few weeks you won’t see much happening but keep feeding lightly with a pinch of spirulina or a small amount of phytoplankton and you will suddenly find you have hundreds!
In larger containers, water should be changed once a month, and more often for a smaller container.
Culturing copepods isn’t that hard. However, overfeeding is a common reason many cultures fail. As long as the water is only lightly coloured and not a very dark green, then you will have more success. Similarly, the water needs to remain coloured so there is always food available.
