Hey, it's been 30 years since my last SW tank. Things have definitely changed! I am setting up a 60 gallon, probably fish only, at least for now. I used RODI water, canister filter, salinity is 1.020, temp 78°. Friday I added live sand. Saturday I added Tim's stuff. I checked my water for the first time last night (Monday) and my PH was 7.8, ammonia 0, nitrite 0, and Nitrate was 5. I may be confused, but I'm thinking I should be seeing the ammonia spiking and seeing nitrites rise and so on. So is it possible this has already cycled since nitrates were 5? Thanks in advance, Lauren
