You must be patient, it could take as long as 6 to 8 weeks for the tank to cycle, should be shorter with the LR but you're still looking at 4 weeks. The other thing is your looking for your ammonia to spike not PH, then the nitrites will increase and your ammonia level will drop to zero, after the nitrites spike your nitrates will start to increase and your nitrites will begin to drop to eventually to zero, when your nitrites reach zero your tank is considered cycled at this point you must perform a 50% water change then you can begin to add livestock a little at a time to allow the beneficial bacteria to increase to handle the bio-load. Do you have a test kit? If not you're going to need one that tests for Ammonia, Nitrites, Nitrates, PH & KH to start with for a FOWLR if you plan on keeping corals there are a bunch more test kits that you will need.
I'm sure the members will chime in and fill in the blanks as I to am new to SW as well and am starting with FOWLR.
