Tidepool Tim says,  “Gulf of Maine Brown Seaweeds is a great way to introduce students to a variety of seaweeds or marine macro-algae. Various species of kelps and "rockweeds" (Ascophyllum and Fucus) are supplied. A minimum of 6 species is supplied with enough volume to run a classroom of lab activities or experiments. Algae can be kept in refrigerator temps for up to a week. Students may want to make mounts and dry the specimens for display. Seaweeds are shipped as "catch of the day" depending on the time of year and relative abundance of species.

This assortment is also sufficient for establishing a diverse brown seaweed presence in a saltwater tank.  Investigate for yourself which species 'like' your tank's specific environment."
