Well it is good that you havent added any live animals yet. Where to start..
First off you need some test kits. Initially I would recommend kits for the following:
Ammonia, Nitrite, Nitrate, PH
, Alkalinity. You will also need a salinity meter. Test kits vary with accuracy and ease of use. I would recommend salifert test kits, they are the most accurate out there. (although expensive they are worth it. They are the only way you know what is going on in the tank.)
Lighting will determine what you will be able to keep in the future. If you want mushrooms, soft corals, zooanthids etc power compact lighting should suffice. If you want small polyp stony (SPS
), Large polyp stony (LPS
), or clams more light will be required. I suggest you pick up some books (i would recommend "The modern Reef Aquarium by Julian Sprung and Charles Deelbek" as a good starting point.
Adding powerheads (PH
), or some form of waterflow in the tank is essential. I would place one PH
near the top of the water column directed at the surface, and one on either side of the tank facing each other to start.
You do not need any additives at this point, and until you can test your water you wont know what you need
Patience is the key. How long ago did you add the rock and sand? Shoot me a PM and i will answer any questions you have.
