You don’t need an ammonia test after cycling, your ammonia cannot drift out of whack
your reef has no ammonia problem case closed. Ammonia control issues do not persist after cycle completes, it cant undo, your problem is now fixed. No need to buy any new tests to determine something already known. Look at what ammonia reads on day 30 of a cycling chart
*when you run another test that isn’t seneye and get more ammonia confusion despite what I’m typing above, that too will be a false reading
the video link above doesn’t work but we don’t need that to know your ammonia is safe. No reef can have it unsafe at month four, not possible in reefing, see any cycling chart
