Just want to get an idea of which one is used more often and reason behind it? I have used both I am like CoralRX better. I feel that lugol's might be too harsh on corals and I have had zoas that never open up again (and melt away) after I dip them in lugol's. On the flipside, CoralRx doesn't list whats the active ingridents so how does one know if it really works as in killing all pests on the coral?
Thanks in advance.
