    Will a lower ph help increase the speed of cycling or no difference?

    Having tap water with a ph below a 7.0 will have a longer cycle process. Having tap water with ph below 6.0 will not even cycle. With that said, your PH will fluctuate during the cycle process and go below as the result of waste.

    What is your PH?

    "The other big problem is that the cycling process seems to stall with ammonia or nitrite not dropping anymore. Usually this is due to a low pH value (less than 7.0). The conversion of the ammonia and nitrite by the bacteria naturally produces an acid that will lower the water pH. If the pH gets too low, however, the nitrification (cycling) process will stop. So if you add a lot of ammonia over the course of a week and get the cycling cranking, you can actually cause the pH to drop to a low value and ‘stall’ the entire process. The way to get the cycling going again is to simply do a 25 to 20% water change. This will increase the pH and usually gets the cycling process going again."
