in my opinion the key portion left to discover is whether or not untested tanks who also setup giant rocks stacks in the middle of the display and circulate water fast across surfaces behave with any different cycle control dynamics than tanks we can verify on seneye
old cycling science says each tank is subject to highly varied cycling outcomes-you must test each tank individually to know when its ready, to predict it's start date.
new cycling science says we're all connected, in scale, even a 1 gallon pico reef or a 1000 gallon display pro setup and even if there's no ammonia testing, we know what rock stacks can do - in any container.
its fun that we get to make predictions and then let the advent of digital nh3 testing take over the hobby and be the ultimate claims filter about predictions. So many hundreds/thousands of seneye measurement logs are available for the scoping we can learn all about bottle bac, live rock skip cycles, tank transfer cycles etc.
all from never owning the gear :)
