​​
      Setup Your Culture Vessel​​

• Fill your container to 1/2 full with freshly mixed saltwater (SG 1.018–1.020)

• Add an airline and install air pump for gentle bubbling (avoid violent turbulence)

• Temperature: 25–28°C (77–82°F) is ideal but room temperature is acceptable
  
  Introduce Your Rotifers​

• Add your starter culture (1-5L recommended)

• Wait 3-4 days before harvesting to allow them to acclimate and begin reproducing
  
  Feeding the Rotifers

• Avoid overfeeding – excess food can cause water fouling

• Add the desired about of roti-feed until your culture water is a light green colour

• Ensure you are feeding multiple times daily with phytoplankton or a pre-made rotifer feed​​

• Always refrigerate your phytoplankton or rotifer feed if it is not being used or actively cultured

​

      Harvesting

• Pause air-pump operation, allowing debris to settle (remember to re-activate power after harvest)

• Use a 53-micron sieve to collect rotifers, pour culture water into the sieve to collect

• Once population has built up and is thriving, begin harvesting daily (avoid overharvesting)

• Rinse with clean saltwater and feed to larvae or enrich with supplements if needed

​

      Weekly Maintenance

• Wipe the culture container walls using a cleaning brush, or similar

• Siphon out debris from the bottom (dead rotifers and waste build-up)

• Perform a 50% water change, in low populations to save rotifers, siphon these into your 53 micron sieve

• Top off with clean freshly mixed saltwater at your chosen culture water 

• Check salinity and pH regularly. Ideal pH is 7.8–8.2 and 1.020 is an ideal s.g
