Mini cycle

[fishinstaller26]

I recently moved my community tank from its 55 to a 72 when the previous fish outgrew the tank
I did 50 percent water change. Cleaned gravel well and replaced carbon in filter

I am now nothing that I have 0 ammonia .25 nitrite 0 nitrate
I did a water change brought everything to 0
The next day nitrite is now at .25 again with everything else at 0
Is the tank mini cycling since the tank has been set up for 5 years before moving these fish in

Something's fluffed your cycle... is it normal for you to see zero nitrate?

Yes, I believe it is mini cycling since you "cleaned your gravel real good" and changed the carbon. Should clear up fairly quickly though.

Thanks guys it has to have cleared up everything is back to zero

 

[TeenyFish]

Everything at zero is typically not good though... you should be showing some nitrate if your tank has cycled...

Could it be that the live plants and algae in the tank are taken up the nitrates

 

[fishinstaller26]

Since the tank has be set up and running with fish for 5 years before I moved these fish in

My mistake just checked water with a tetra 6-1 test strip and nitrates are at 40ppm
