I was wondering if my tank is cycled? It is a 90 Gallon aquarium that I started with all Reef Saver Rock from Bulk Reef Supply. 90lbs. I used Dr. Tim's bacteria and added two clownfish 19 days ago. They have done fine and have been eating everyday and seem healthy. Ammonia spiked as high as .5 PPM
and have been at 0 for the last five days. Nitrites have gone as high as 2 PPM
but are have been at .5 for the last 3 days. Nitrates are at 40 PPM
. PH is 7.9.
Is my tank cycled? Do I keep waiting for Nitrites to hit 0?
