here's 23 pages of the exact work:

the benefit of that bulk work is patterns in the new setups, how we controlled cycles on all of them and never used ammonia testers along the way. What is true is usually opposite of what most people feel comfortable doing, so highlights from the work thread are (hey can we have your pics and documentation too/add to the work):
-if you move dirty substrates over, a cycle is likely.
-if you move 1000% clean substrates over, those rinsed totally clear of detritus, then no cycle will ever happen for the next 23 pages
-our hobby is absolutely built on fear of loss of bacteria, that never occurs to a degree of instability. It occurs to the degree of .25 ammonia when tested, just like most running tanks we can see in threads... detritus is what kills peoples tanks as they hesitantly move/clean in order to preserve bac they thought were weak
-live rock will never cycle when you just move tanks. My whole reef is drained for 30 minutes in that thread for recurring proof of this. its 13 yrs old and had about 1000 drains. record is 33 mins in cold winter air/refilled/no cycle
-you can replace, leave out, rinse, reuse, do anything you want to do to the live sand just don't move over clouding detritus. slice it anyway you want, if you move waste you risk loss and if you don't, you have 0% chance of system loss
-you can buy or use bottle bac if you want, we have never done it. Total control over your tank bacteria is demonstrably possible. we hesitate never, at any phase, and predict ahead of time what happen with bacteria and test readings then after pics and vid show it in the thread.
-when you set up your new tank don't run the lights as full production normal, ramp them up for a week like you just got new lighting.
its not that cycles occur sometimes, or iffy, or unpredictably. they occur when we simply don't factor detritus where it exists.
