My Tank Thread
I would get that Iodine level down asap and figure out what is adding it - that will crash your tank really fast. Do not let that get over 60.
I would also put a polyfilter in your chamber where you keep your carbon (start using carbon asap if you dont already and replace it every 2 weeks) to strip out the Lanthanum. Replace the polyfilter whenever it starts to brown.
Im not sure how urgent it is, or even if it is accurate, but the hard cap at 60 ug/L iodine seems overly extreme since even natural seawater will be higher for any salinity above 35 ppt, and iodide/iodate are not particularly toxic.
