Mike here is the new way being used to cycle just under forty pages of reef tanks without using testing
Updated Cycling Science in Action This is a testless reef tank cycling thread, the only one from any board. If you ever had trouble with reef tank cycling in the past, you won't any longer after working some jobs with us. chances are you are using/about to use a method of reef tank cycling...

the new way is by knowing # of days underwater
they still post test readings in the thread because that’s how we’ve been trained to assess cycles, but I’m not factoring the test levels in assigning their ready dates. I only get their # of days underwater for that portion
testless reef tank cycling that is ready on a specific date for each tank is the new way

no sticks, stalls or starved cycles above.
Jacob that was a great way to cycle for sure. your tests happened to confirm the ammonia drop, after the number of days we know ammonia drops occur even if we didn’t get so lucky for your non digital test kit to show it.
*that thread above is ten day waits, you’re ~ five times beyond our measure interval = you’re cycled
I was assessing surface area by your picture (it has plenty) and water clarity, no need for the big water change here you’re already underway reefing. Bottle bac works this well, agreed.
