Easy reefs® Rotífero
Easy Reefs ® Rotífero has been developed for the culture of rotifer.
Net content: 15g.
Preservation. Store Easy reefs ® Rotífero in a dark, dry and cool place. The storage temperature should not exceed 25°C. In summer, if temperatures are higher, it is recommended to store it in an air-conditioned room.
Once the container is opened, it is very important to keep the biomass dry and in darkness. Avoid storing it in places that are wet or high humidity, do not store it in the refrigerator (condensation when opening the bottle causes the microalgae to absorb moisture and degrade). Keep the bottle closed. Once opened, consume preferably within 4 months.

Two Easy reefs ® microalgae species (Nannochloropsis 80 % + Tetraselmis 20 %) to ensure the correct growth of rotifer.
The average consumption is 100 mg per litre of rotifer culture per day harvesting a 25 % of the rotifer daily, although the dose depends on the rotifer density achieved.
To maintain a rotifer culture, follow the following directions:
Material needed: 3 cylindrical recipients of 2 L with soft aeration, using a hollow rod. Initial rotifer inoculum.
Necessary feed: Easy reefs ® Rotifero: Nannochloropsis (80 %) + Tetraselmis (20 %).
Culture cycle from strain: 5 days
Recommended water density: 1019, although it can grow well up to 1024.
Optimum rotifer culture temperature: 22°C to 25°C
It consists of a parallel culture system in which after day 6 continuous food is obtained for the aquarium. One jar for the strain and another jar for production.
The resuspension of the algae has to be done with a blender following the resuspension instructions with a volume of 0.5 L of seawater.
The information that follows describes the dosage to be used in ideal conditions, assuming that the rotifer density is the ideal. It is possible that sometimes the amount of seaweed added does not match the rotifer’s demand. If the water remains clear, this indicates that the dosage not sufficient. When rotifer remain without feed for more than 4 hours, the number of eggs decreases, and therefore the population growth rate decreases as well. It is essential that rotifers always have feed available.
Rotifer is very sensitive to changes in the physical and chemical parameters of the water. If water quality worsens rapidly, rotifer population will be affected. If excessive dirt is seen in the recipient, filter the rotifer, inoculate it in a clean recipient and add the necessary algae.
With experience, the intensity of the green color will indicate the amount of algae needed, and you could even develop your own protocol. There is no difference between live or free-dried microalgae to be used as feed, however freeze-dried microalgae are dead and the decomposition period is shorter, so we must be careful with the quality of the water.
A 5 mm diameter rod with very gentle aeration (about 5 – 10 bubbles per second) is introduced in the culture recipient so that there is a homogeneous mixing of the culture. Excessive turbulence causes the rotifer to lose the eggs and they will not hatch.
It is advisable to distribute the feeding dose in two or more feedings per day, but for time reasons it is usually fed once a day.
DAY 1
Initial conditions: “strain” culture with 1000 ml of sea water, number of rotifers 400 rot./ ml to 600 rot./ ml and 100 mg of Easy reefs ® Rotífero Nannochloropsis (80 %) + Tetraselmis (20 %).
Instructions: Resuspend 100 mg of Easy reefs ® Rotífero in 0.5 L of sea water (follow instructions) and add to the recipient. Add the rotifer inoculums and add sea water until the total volume is 1 litre.
DAY 2
Initial conditions: 1 L of rotifer culture. It will be nearly clear and with no microalgae. Estimated rotifer number: 500 rot./ ml
Final conditions: The culture will end up with a volume of 1.4 L with microalgae.
Instructions: Resuspend 100 mg of Easy reefs ® Rotífero in 0.5 L of sea water (follow instructions) and add 0.4 L to the rotifer culture.
DAY 3
Initial conditions: 1.4 L of rotifer culture. It will be nearly clear and with no microalgae. Estimated rotifer number: 500-600 rot./ ml
Final conditions: The culture will end up with a volume of 1.8 L with microalgae.
Instructions: Resuspend 200 mg Easy reefs ® Rotífero in 0.5 L of sea water (follow instructions) and add 0.4 L to the rotifer culture.
DAY 4
Initial conditions: 1.8 L of rotifer culture. It will be nearly clear and with no microalgae. Estimated rotifer number: 600 rot./ ml
Final conditions: The culture will end up with a volume of 2 L with microalgae.
Instructions: Resuspend 300 mg Easy reefs ® Rotífero in 0.5 L of sea water (follow instructions) and add 0.2 L to the rotifer culture.
DAY 5
Initial conditions: 2 L of rotifer culture. It will be nearly clear and with no microalgae. Estimated rotifer number: 700-800 rot./ ml
From this “strain” culture we will get a volume of 0.5 L to start a new “strain” culture in another 2 L recipient and start a new culture cycle from day 1.
We will add microalgae to the old “strain” culture, from now on “production” culture, until it reaches 2 L. If the cylinder is very dirty then we will pour the culture to a clean recipient and carry on with the production culture.
Instructions: Add 200 mg of resuspended Easy reefs ® Rotífero in 0.5 L of sea water to the “production” culture. For the “strain” culture start a new cycle from day 1.
DAY 6
Initial conditions: “strain” culture the same as day 2. “production” culture 2 L with 800 rot/ ml, it will be nearly clear and with no microalgae.
The “production” culture would be used to harvest 0.5 L every day and be used as food for the aquarium (if you do not feed the aquarium, you must do the harvest anyway so you can feed the rotifer with microalgae). If you harvest 0.5 L of rotifer you always have to add 0.5 L of sea water with 200 mg of resuspended Easy reefs ® Rotífero. The “production” culture will be kept until the recipient is dirty (5-7 days).
When the “strain” culture reaches day 5 of culture it will be converted to the “production” culture and a new “strain” culture will be created, the same way as it has been explained on day 5.
**Sometimes if the rotifer number is low the “strain” culture will not grow well when a new culture is started. To avoid this, we recommend to get 0.5 L of the “strain” culture on day 5, put it in a clean recipient and start the “strain” culture in the following way:
We will add 200 mg of Easy reefs ® Rotífero resuspended in 0.5 L of sea water
Resuspension instructions
Easy reefs ® are freeze-dried microalgae so it must be hydrated before being used. For correct hydration follow the next steps:
- Put sea water as specified in the directions in the glass blender.
- Add the amount of Easy reefs ® as specified in the directions.
- Leave Easy reefs ® microalgae to hydrate for one minute, with no mixing.
- Run the blender on a gentle speed for one minute.
- Add to the aquarium as directed.
One level spoonful = 100 mg of Easy reefs ® microalgae
Only prepare what is to be used. It is not recommended to store what is left after resuspension. Even in the refrigerator nutritional properties are lost due to oxidation.
Nannochloropsis gaditana
- For its lipid profile rich in EPA and ARA.
- Thanks to the enzymes produced by rotifer to dissolve the cover of this algae, an earlier maturation of the digestive system of the fish larvae takes place.
Tetraselmis Chuii
- For its high antioxidant content Superoxide Dismutase, Catalase and Glutathione Peroxidase.
Increases rotifer fertility
- Easy reefs ® is 100 % freeze-dried marine phytoplankton, thus obtaining from this product all the advantages of microalgae in an easy way. With Easy reefs ® you can obtain excellent results in your zooplankton culture.
