RG Complete

RGcomplete is a super-concentrated microalgal-based premium quality feed and enrichment for rotifers and other filter-feeding invertebrates. It has been sized especially for Breeders, Aquarists, and Propagators and includes both a pH buffer and ClorAm-X® (ammonia neutralizer). It has a long refrigerated shelf life of at least 6 months.

Features and Benefits

refrigerated, not frozen
Includes ClorAm-X (ammonia control and a pH buffer
Clean, high yield rotifer feed
Maximizes levels of DHA, EPA and ARA
Stand-alone feed or in combination with one of our enrichment products
Suitable for a wide range of zooplankton
Fully intact cells
Cell size range 1.5 – 12 µm

Use and Storage


Refrigerate (33-42°F / 1-5°C)
Do not dilute for storage

Best Before Date (Shelf Life)

6 months

Rotifer Culture Directions (100 – 250 rotifers per mL)

Feed enough to keep culture water light green
Feed twice or more a day
For maximum productivity, do not let water go clear

Advanced Directions

Feed 11 ml per day per 1 million rotifers to be harvested. For example: Population of 5 million to be harvested at 20% per day, or population of 2.5 million to be harvested at 40% per day, etc.

Maximum production requires higher density cultures, which require more frequent feedings. For best results feed at least every 3 hours using a pump and timer.
