Zero Nitrates After Cycling
So I have a 10gallon planted tank I plan to stock with a Betta that appeared to complete the cycling process a few weeks ago. Since the tank is planted and some small snails hitched a ride on my new plants I let that be my starter ammonia source and let the tank run. I used an API master test kit to test the water every week and saw a spike in ammonia and nitrates, but eventually I had 0 ammonia, 0 nitrites and about 10-20 nitrate. Just as the tank cycled my state imposed a stay at home order so the tank has still been running unstocked with weekly water changes, and Flourish and Neutral Regulator added. Since I need to go to the pet store now to stock up on cat food I thought I might pick up a Betta while I'm there, but when I checked my water just now I got 0 ammonia, 0 nitrite, and 0 nitrate. Can my tank still be cycled with 0 nitrate? With the plants growing in and snail poop accumulating I find it hard to believe the tank is no longer cycled, especially since my ammonia is still 0.
Any thoughts would be greatly appreciated!
