The algal balls will arrive stored in a container of distilled water.
The Chlorella within the balls is alive and therefore needs light to stay active. We recommend that you leave the balls in the container that they arrive in, and that you place this vial in a well lit area until required. Do not place in direct sunlight, nor expose to hot light sources, as the heat will be detrimental.
It will also help to loosen the lid of the container to allow air access. However, take care to protect the container from being knocked and subject to leaking.
For best results, use the algal balls as soon as possible, but in any case within 2 weeks of receipt.
