Fishless Cycle Has Not Taken Off, What Can I Do?

[Nosnibor]

Actually, in reading more articles, I have learned that the optimal pH for nitrification is between 7 and 8 and the process severely slows as pH drops toward 6.0. Below that level, the bacteria go dormant and the cycling process stops. So although pH does seem to vary greatly during cycling, it is worth testing pH occasionally to make sure it isn't dropping too low, especially if things seem to be going slow or are stalled.

You're totally right rrd1952, my PH has dropped from 8.0 to 7.0. I was surprised but tested after you first mentioned it on your fantastic fishless cycle topic.
