OK. Find out where you can get ro/di water.
1. Buy live aragonite sand if you can find it. Live rock at least. [I used dry bagged aragonite sand and live rock and it worked great.]
2. you may find putting eggcrate (that overhead lighting grid) down as a flooring before sand may stabilize your rocks better.] Cut it with dikes.
3. Mix your saltwater. A maxijet 900 with a 6 foot hose to use at need works great as a mixing and water-change pump. 1/2 cup per gallon of ro/di water will give you about 1.024 salinity, which is good. Test it to be sure: a refractometer is the most accurate, and fastest.
4. Fill your pod up to 4 inches with sand. Add a little salt water, add and arrange your rocks. Add more water. Do not pour: pump it in, with the hose end aimed at the side of the tank to prevent cavitation of the sand. It will be totally cloudy for days.
5. Turn on your heater and your pump. Rig a thermometer. Have two: they're unreliable as all getout, and your heater thermostat cannot be trusted. Do not use lids anywhere in the system. Heat is a killer.
6. Add 1 tiny pinch of Formula One flake food per day.
7. Wait a few days. After the water clears, test for nitrite, nitrate, and ammonia. Salifert is my test of choice. The strips are too vague. Keep testing every few days. Use this interval to research the fish you want and read up on tank chemistry.
8. Test until you see ammonia and nitrite and nitrate, and go on testing until it reads 0,0,0 respectively.
9. Let it go a few more days. Keep feeding your imaginary fish and keep testing. If it stays 0,0,0, you're ready for inverts.
10. Get one snail or hermit per gallon to clean up the algae. When you add livestock, put the bag in a bowl in the sink, draw off a cup of your salt water, diminish the water in the bag until it's about a cup, and mix the two over the space of an hour or two. Then net the critter in the bag and transfer him to your tank. This particularly goes with the shrimp. They're fragile.
11. Go on testing. Stop feeding: the algae should sustain the cleanup crew. If you stay 0,0,0, get your shrimp and wait a few days. When adding fishes, except for pairs, put them in singly and wait a week. Many reefers quarantine, ie, put them in an observation tank for a month before they go in, to be sure they're not carrying any disease. Be very selective with your fish. Get the fish store to feed them, make sure they're eating, find out what they're eating, and look for signs of disease: white spots, hollow belly, etc. You want fat and active, and don't get a fish if there's disease in the tank. Be extremely picky. Don't get fish from a chain store, if you'll take my advice. Find a good reef shop run by someone who knows what he's doing.
12. Tankbred clowns or nanofish are your best bet. Nanofish are an array of small, colorful and generally peaceful fishes, less aggressive than clowns: look at Foster and Smith's catalog for a sample of the type. Don't plan on an anemone for months. They're not something to have in a tank that's in the break-in period.
Test every few days, and you'll be also topping off with fresh ro/di water to maintain salinity against evaporation. Do a 10% water change with salt water every week. Keep a log book of your readings and anything you add, including when fish arrived, etc.
I hope this gives you something to go on.
