i've been adding 1 drop of lugols to my tank once a week. i know this isn't near whats reccommended for my water capacity(around 85g), but i don't want to overdo it. especially since i use IO salt, which is high in iodine in the first place. is it true that carbon takes iodine out? i don't have a iodine test kit(heard they aren't very reliable), but i really don't want to overdose. maybe it's just me, but i swear everytime i add the lugols, the color on my zoa's and softies seems to intensify. should i keep adding the lugols? or am i setting myself up for disaster?
