Hey everyone, I’ve tried searching before posting this question but I haven’t found an answer specific to my issue. My tank is 9 weeks old with only fish and I am trying to stabilize my alk before adding coral. I am using Trident to test parameters which I have calibrated. I dosed Alk to 8.5 but it keep dropping back down to 6.5 over two days. I setup my DOS to dose two part solution of ESV 3 ml every day for 140g tank and I still can’t keep a consistent 8.5. I don’t understand, what’s consuming all this alk? Is this precipitation?
