I suspect like most organically fed (fishfood, prawns, anything that the heterotrophic bacteria have to break down to make ammonia) your fishless cycle will be bit harder to predict and to kind of know where you stand as to progress. Just like any type of cycling however that just means it's important to have patience on a continuing basis and to continue to post observations and refine your understanding of the goals and whether you're reaching them. For us old-timers, the wonder of fishless cycling is watching that first batch of fish behave as if they are in their favorite environment. They all really like having "double-zero" water!
Hey friends, thanks for the kind comments but I'm not any more of a cycling guru than any of you can be if you combine studying the topic with a few years of reading people's cycling experiences and caring to share these experiences with other newcomers to the forum. I'm one of a number of what I call "re-beginners" who had previous stretches in the hobby (as opposed to hobbyists still on a decade or more of continuous activity in the hobby.) In my case I get to combine experience centering in the 60's/70's with what I've learned in the past 3 or so, which is sometimes helpful, sometimes not.
There are plenty of hobbyists here (many of the mods and others) who have a greater volume of useful and practical knowledge of the hobby than me. Many of them have multi-decade experience tying straight on in the current period. One of the fun things about exploring any topic with multiple people are the different experiences and insights people will bring.
