That is very interesting, it appears that by using ASW you are adding a SUBSTANTIAL higher level of trace elements than you would by using NSW.
Lets take, ohh say Iron for example (in micromoles per kilogram) NSW = 0.0001, ASW (instant ocean) = 0.24. You could be dosing substantially higher levels of iron than, hmmm, lets see, say Zeovit? :lol: Then again, take Seachem's salt, a whopping 7.7 mm/kg of iron, ouch!
