Google how to properly cycle a saltwater tank that is the first step and usually takes about 4 weeks to complete before you can add livestock. Patience and research is key in this hobby.
In short form
-put live rock in tank
- add sand
-add saltwater that is already mixed
-put in a cocktail shrimp and let it rott.
- monitor parameters daily
Watch for a spike in ammonia, then nitrites, then nitrates. This could take days or weeks I found it best to give it more time then less.
-add a small clean up crew.
- wait another week or so ( give the beneficial bacteria time to grow to the amout of livestock you have added)
- add a fish
It is good to add small amounts of livestock at a time so as not to overload your biological filtration. It gives it time I between to catch up.
Ya might need a heater as well to keep your temp at 78-80 degrees depending on where you live.
And that was short form!! Lol any questions just ask. I've got a jbj cube and I love it. Good luck
