Hey guys! Im upgrading my saltwater estuary tank. Its a brackish water tank at .17 gravity. It can get up to 20 with evaporation over a few days. I top it off with fresh water. The focus of the tank is my horseshoe crabs. I have 4 and have begun acclimating dwarf hairgrass and another grass to the brackish environment as well as some cherry shrimps and common pond snails. Its been a week since I started and the shrimps are at 10. So far Everything is going well. The grasses are still alive and so are the shrimps and snails. The snails are actually wild cought from here in oklahoma but their species varies in its range and they can be also found where fresh water mixes with salt water. Im open to suggestions for stabilizing a bioactive ecosystem. Im gonna get a mangrove in there as the final touch!
