Tropic Marin has a new product that is being fleshed out to their European counterparts. The “shake and make” system is an interesting twist for new hobbyists that get attracted to keeping saltwater aquariums. The device is a ship-flat plastic container that expands and holds roughly 5-10 gallons of water. However, inside the container is a pre-measured amount of Tropic Marin’s reef salt that can easily be shaken and mixed before being introduced into a saltwater system. Tropic Marin says this product is designed for people that are new to our hobby and should be hitting local fish stores later this year at an unknown price point. There will be two versions, a nano (pictured) and a full size for larger aquariums.
