I don't think it will hurt to add the bacteria. It may not help, but I doubt it will hurt.
I would start testing ASAP so you know if/when your cycle is complete, and it's safe to start stocking. You should see a small
ammonia spike, followed by a
nitrite and
nitrate spike due to adding the new
LR and LS. Like Carmie said, if you don't see an
ammonia spike in a couple of days, toss a piece of raw, unseasoned shrimp in the tank for a couple of days to kick things off. Once
ammonia and
nitrite test at 0 for a couple of days in a row, do a small water change, and begin stocking with a few snails/crabs and maybe a shrimp. After another week of steady water readings, you can add your clowns. I will add at this point, that a 10-15 gallon tank will be pretty much fully stocked with a pair of clowns and a handful of snails/crabs/shrimp. You could maybe get away with the anemone once you upgrade to the proper light.
As for the water. You mean you are mixing your own saltwater, correct? Are you using plain old tap water? If so, that's a no-no. It's typicaly cheaper to mix your own water, but you'll either want to buy
RO/DI water from the
LFS, buy a
RO/DI unit and make your own, or use distilled water from the grocery store. Tap water contains all kinds of chemicals and metals you really want to keep out of your tank.
