If that is the case - why are folks like dr tim, mr saltwater tank, and madmatter reef (his was a 200+ gallon tank) saying it " can " take 7 days or less.
Can is a key word here. Depends on rock, sand, temp, light, salinity, "bacteria in sand , rock, air and the tank" before you added water... and the salt water gods. Lots of variables.
Curing pukani was an option for me - but I didn’t go that route because there was an import ban at the time and no one had it in stock so I went the dry macro + Dr Tim method instead.
And this was a fine way to go.
So in Jan I started cycling some rock for a tank. It was dry marco. 1 bottle of Tims per 100 gallon tub. Dosed ammonia. Added a table shrimp in each tub just because im old school. Added a powerhead. It took 3 weeks in the cold to cycle enough where I felt it was ready to go in the tank. I spoke with many people that cycled marco rock and all seem to agree that 3 weeks was the time period.

If anyone wants an instant tank, you need live rock with no die off. Even then you might have a mini cycle.
