Frequently Asked Questions
Bioluminescent algae live for approximately 1 month. To extend the lifespan of your algae, purchase additional growth medium. Bioluminescent organisms can live indefinitely if provided with new growth medium.
- Additional Growth Media for Algae
To use, gently shake an existing culture of algae, dispose of 75% by volume, and replenish to original volume with new medium. Repeat this process every 1 to 2 months, or when bioluminescence begins to fade for 2 to 3 consecutive nights.
- Bioluminescence Index
The intensity of bioluminescence is scored on a scale of 0 to 5. A value of 5 signifies potent bioluminescence, and a score of 0 signifies no visible bioluminescence. Scores of 1 and 2 require the eye to be dark acclimated to observe bioluminescence. Scores of 3 and above do not require dark acclimation of the eye to observe bioluminescence. The Bioluminescence Index for each specimen can be found under the Additional Information tab of the product page.
- Order Dispatch and Delivery Times
Orders are dispatched for shipment within one to two business days. If an order containing living specimens is placed late in the week, it will be shipped the following week to avoid weekend delays. International-bound shipments are dispatched on the following Monday to ensure delivery prior to the end of the business week. Shipment times are subject to product availability, and customers seeking bulk quantities of algae should contact Empco prior to placing an order to confirm delivery commitment times. Express shipping implies diminished transit time for living specimens, and does not accelerate shipment dispatch time. Please email Empco in advance if your order is urgent or time sensitive and we will confirm a delivery commitment date.
