Heyo! I recently set up a 38-gallon tank using 2-lbs of Gulf live rock rubble and 15-lbs of base live rock from TankStop (based in LA, so shipping was easier and affordable). Both arrived wet, the Gulf rock smelled “oceany” but not overly pungent, though the rinsing bucket turned cloudy, so I’m assuming some die-off occurred. I also added mature sponge filters, and the rest of my rock was dry but soaked in a heated, aerated bucket with those sponges for a week while ghost feeding.
This is my first time starting a tank with a solid amount of live rock, so I’m clarifying my observations: Yesterday, I dosed 0.2 ppm ammonium chloride. Given the rock die-off, I’d expect to see ammonia build-up if the rock bacteria weren’t sufficient to process it. But after 12 hours, I’m measuring zero ammonia and only trace nitrates.
Does this mean the nitrifying bacteria from my live rock are already effectively processing the ammonia? Should I wait another 12-24 hours before concluding the ammonia is fully processed, or am I overthinking it? Thoughts?
