Don't worry about asking questions, we all had the same ones as you do.
You will want to get a test kit. I like the API saltwater test kit for starters. It has your ammonia, nitrIte , nitrAte and pH tests (don't worry about the pH testing until your cycle is complete).
If you have cured LR
, you may see little to no cycle.
A typical cycle will need a source of ammonia. I like to use 1 raw, unseasoned jumbo shrimp per 30 Gallons. Once it starts to decay, it will produce ammonia (you can use fish food as well). The ammonia should spike and then your nitrItes should rise while the ammonia declines. Next you will see nitrAtes rise and your nitrItes decline. Once you read 0 on ammonia and nitrItes, do a PWC
and your tank is cycled.
