For a
FOWLR you wont need any special lighting other than a dual strip florecent light. You would need the following equipment to get started.
Sea salt mix
heater (unless you can keep the water temp at 80F with out)
small hang on back filter (minibiowheel maybe)
2 small powerheads (~100GPH each)
It will be hard to find a skimmer that will fit on the back of a 10 but I belive the prizm skimmer will. The skimmer is not needed but honestly for a saltwater beginner its stronly suggested.
Hydromoter so you can measure the salinity of the water.
10-15lbs of live rock
3" sand bed
Other assorted items include:
Ammonia,
PH, NItrite, Nitrate test kits
Some fish only buckets. YOu can use one of them to mix saltwater in. A heater and powerhead for the mixing bucket also since you should get the water change water up to tank temp before doing a water change. Plus warm water disolves salt better.
I cant help but stress that a 10
gal tank is not a size recommended for beginners. Now that does not mean you wont be sucessful. I know people who have started with even smaller tanks and done well. But what it will mean is diligent watch over water levels during the cycle and the first few months after. Additional needs will be daily topoffs with freshwater to replace evaporation.
You should also be aware of the stocking limitations of a small tank. I would not suggest any more than 2 small fish (~1" in size each).
