If it high alk in your tank just let it drop on its own. If it’s In your make up water then a couple drops of murriatic acid will do the job nicely

No. Not to mention ammonium is preferred by the coral. I myself dose ammonium and is the better choice for nitrate limited aquariums

Lanthum products are fine AS LONG AS YOU KNOW WHAT YOUR DOING!!! Should dose into 5 micron sock or dose into skimmer.

It’s not that’s it’s toxic, it’s that when the lanthum reacts with the water it creates a fine particulate that can irritate some fishes gills

I get it, but after the bleaching it should be rinsed and soaked after as well to help limit exactly what you’re going through now
