Mainly folks need to know that ammonia isn’t expected to be zero, that’s the old rule that gifted bottle bac salesmen unlimited extra sales from misadvised click buyers. I think one of the key, key takeaways in updated cycling science is that even if red sea is ran exactly right per directions, and someone gets an estimated .4 reading instead of the classic .2 from running reefs, it specifically doesn’t mean their cycle is stalled.
nobody measuring on digital kits gets that issue, stalled cycles, it’s strictly a realm for non digital testing.
if someone says their ammonia clears overnite, and another party says theirs clears to zero in 3 days, it specifically does NOT mean one party has a stuck cycle, it means that’s the variation in testing accuracy both tanks show- on hanna or seneye they’d both be on spec.
counting the # of days underwater factored against Dr. Reefs study thread on # of days timing / they’re all done by day ten maximum worst case scenario / beats any form of non digital horseshoeing in my opinion
non digital ammonia testing will indicate a false stall to nearly everyone, causing them to lose track of fish disease focus and fish accclimation, the real killer. ammonia control issues don’t occur in display reef cycles. Sounds crazy am aware

let’s give it 25 months more for the digital test rollout to continue to inspect that claim.
