Receiving your Rotifers and setting up your Rotifer Culture
Once you receive your shipment of rotifers use the following protocols to make sure you get the best survival rates:
- Open the box and store the bags of rotifers in a refrigerator (39-46 °F, 4-8 °C) until you are ready to put them in the rotifer tank.
- These rotifers can be cultured at pH 6.5 - 8.5, optimally at 7.0 - 8.0 and 60 - 86 °F (15-30 °C), optimally at 79 °F (26 °C)
The rotifers will arrive at a salinity of about 30 ppt (1.023). Your water does NOT need to be adjusted to this salinity - they will adjust into water from 5 to 40 ppt (1.004 to 1.030), although a gradual transition to a much higher or lower salinity is less stressful.
- Take the bag of rotifers from the refrigerator and put it in the rotifer tank for 10-15 minutes to allow it to gradually warm up. Then cut the bag open and release the rotifers into the tank.
- Add enough rotifer feed (see Rotigrow; for hobbyist culture see RGcomplete) to the water to establish a green background.
Check the rotifer tank in a few hours to confirm that the rotifers are feeding actively and thus clearing the water.
