so I have a 5g q-tank. Took the last 4 fish out , 2 at a time , 2 weeks ago. Left the tank running with no fish for the past 2 weeks , yet I still have nitrates . ( am-0, ni-0) ph 7.5.
I thought there must be fish in there or loose the cycle. NI -30. as I said , i have not touched it in 2 weeks.
Want to get more fish, should i do a wc first ? Filter is a AC 50 and an air stone.
Why is the tank still cycled without fish ???? thanks
