Fishless cycling

[NikkiNoo]

Hello, I set up my aqua one reefsy 255 tank about 2 weeks ago with dry rock and live sand.

Added Dr Tim’s Nitrifying bacteria and ammonium chloride last night.

These are my levels this morning. What next? Pic attached

If the ammonia reads low again today or tomorrow, then I'd personally dose 2 ppm ammonia and measure right away (to be sure your device is accurately measuring ammonia), then if that also then drops low like these readings, the cycling is done, IMO.

Thank you. Will do this :)
