I set up an additional biocube 32 with some existing sand and rock. The tank went through a small cycle but has been doing great. I’ve got some macro algae and a small mangrove forest. I got a bonded pair of half spined seahorses from divers den. They immediately ate Mysis shrimp and have been thriving ever since. I’ve also been seeding the tank with baby brine and tisbe pods thanks to a fellow reefer.
