So I'm excited to say we are getting good readings on our 5 week old aquarium. We have 0 ammonia 0 nitrites 80 nitrates before water change ph of 8.0. I'm going to take a sample to the lfs Sunday to see if they agree as this guy has been a trusted place for over 40 years in our area. Then I can finally add fish. Lights were only on for the picture. Will eventually add corals also but starting with fish right now. Looking at a goby, wrasse, or a pair of clowns to start.
