I just started a 10 gallon too. With the usual stuff even tho I went with saltwater:
heater (marina 50watt)
filter (api superclean 5-20)
and one maxijet 400 powerhead to help move the water around. I started with a crappy light meant for freshwater fish, but just bought a double bright LED
18-24 inches that runs white and blue.
I also used about 20 lbs of rock in my 10 gallon tank, some is "live" some is base.
Been cycling my tank with pure household ammonia, but others say use a shrimp (or two). If you don't know what that means, you will have to google "cycling a fishtank"
I also have the API master saltwater liquid test kit so I can monitor the cycle.
When the cycle is complete on this new tank and the water parameters are good, I plan on adding:
1 x ocellaris OR percula clownfish
4 blue hermit crabs
2 arrow crabs
3 margarita snails
2 narc snails
I will have my water checked in a couple of weeks by a professional at my LFS
to see how close I am to being ready for actual livestock. After that, I will be doing partial water changes at least once a week.
