The water vol is diluting ammonia from the rot but it does not matter. you have added bottle bac that allows for fish use right now, search out fish in cycling w seachem. if your tank can house fish now, or after waiting 30 days like a cycling chart shows, your ends are the same. Bottle bac are being fed by your shrimp even if you don’t spike ammonia like all reefers tell you is required, it is not or such volumous search returns would say fish in cycling didn’t work.
when I did that search I found eleven years of fish in cycling feedback all five stars / like all bottle bac it seems to be good quality. Instead of tedious detailing and measuring and spiking more ammonia to follow the masses, a nice mid ground is to simply let your mix stew as is, nothing extra added, for twenty days. Change out some water, begin, at twenty days you’ve allowed for the submersion time a cycling chart shows on the left side.
contrary to popular opinion, you will be cycled right now. Proof, a fish lives. Waiting 20 days is simply extra safety time so the web doesn’t revolt on you lol. This concept would seem insane were it not for twenty pages of fish in cycling I just read using your exact bottle bac. The reason we don’t like fish in cycling has nothing to do with failed cycles, cycles cannot stall or fail. It’s due to skipping disease control we use the shrimp. Your test kits do not apply since you added bac that already fully control ammonia. Envision out of all those search returns, yours being the only tank not working. It’s working fine and I’m not surprised if your zero ammonia is total proof it’s working / no free ammonia is what these organisms do.
This advice is polar opposite of what common advice would relay to you, but that advice would be at odds with google/all seeing patterns cycle eye.
