stalled cycle?

[treshock01]

2ppm of ammonia used to process in 2-3 days. Never saw nitrites. pH remained 7.4ish.

Now, I've been waiting for the same .25 ppm of ammonia to process for 6 days. Still never see nitrites. pH is the same. What do I do to fix this?

Anyone out there that can help?

Just wondering if you have done a recent water change? It just seems a little odd the ph is staying the same (assuming not very hard water / high kh) as ph should drift lower as carbonates get consumed.

I would get the ammonia back up to 2ppm , test in 24 hrs ,
I presume u have oxygen source?, and ur tank temperature is above 20C , ?
And ur ph is above 7 .
And u have fed the tank some fish food etc to provide the benificial bacteria with some minerals. ?

And no more than 30% of the tank is planted .
