So my tank has been running a while to cycle. i finally found a saltwater API test kit and i tested today ammo=0 nitrites=0 nitrates=10ppm. does this mean my tank is finally cycled? i am more familiar with freshwater so just wanted to make sure.
It's very possible, did you use live rock? how long has your tank been cycling? If you want to test it, you can try dropping a piece of raw shrimp in there and see if it spikes any of your levels.
I'd like to know about this too lol. I'm in an identical situation with my "new" tank using my old rock. Hit the diatom bloom a few days ago and all i'm reading now is nitrates.
