I’m really happy to hear that ammonium dosing has made a positive impact to your tank. Are you considering to raise the ammonium dose to get nitrates detectable?I have to agree. I started dosing ammonium chloride 5/25/24 and several acros that were pale with no or little polyp extension have colored up and polyps are fully out. Last test of nitrate was still zero (tested last week). I'm also adding TM phos-feed FWIW.
