I've been doing freshwater aquariums for a pretty long time, but having a saltwater has always been a dream of mine. But I've always figured it would be too hard for me to do, until recently that is. I've been doing a whole lot of research and I figured, why not? So, I went out and bought a 12 gallon JBJ Nano-Cube DX. I also went ahead and got the heater, an Aquatop D1HT Digital Nano Heater. Now, I've got the tank...what to put in it? Well the basics...water, sand, rock. Right? I've done some more research about water, salinity, and all the mixing and such, and with my luck I'll mess it all up. So, I went ahead and bought about 14 gallons of Nutri-Seawater. Hopefully I made a good choice by doing this?? Now for the sand...I went to BulkReefSupply and bought a 10 pound bag of Bahamas Oolite Arag-Alive! Reef Sand. Also hope this was a good choice?? And for the rocks. The Nutri-Seawater and live sand are both supposed to have the beneficial bacterias already in it. And with my research on live rock, the only reason you should get that is if you want to cycle your tank faster, but you run the risk of unwanted pests. But since my water and sand will have the bacteria, there's really no need for the live rock, I hope? I'd rather have dried (dead) live rock than pests that are going to eat my future corals and fish. So I went ahead and bought 10 pounds of Reef Saver Dry Aquarium Live Rock and 2 pounds of Tonga Simple Multi-Branch Dry Live Rock, all from BulkReefSupply. Any input on this?? A side note: I haven't put anything in the aquarium yet, I just have the stuff ready to go. Now onto the fish and coral. I know my tank is rather small so my options are heavily limited. But my plans are: -2 clowns -A small cleaner crew: two hermit crabs, and a shrimp (not sure what kind yet) -Some mushroom corals -Some small polyp corals (perhaps Zoanthus, Palythoa, or Green Star Polyp) Any advice on how to start or thoughts on this would be greatly appreciated!!
