Bottles that say 100% silicone have nothing but silicone in them. That's what 100% means

the GE II i used says "100% silicone". it always has (have used it for YEARS on FW tanks). only now with the new packaging, it also has mildew resistant properties (STILL SAYS 100% SILICONE). i had issues with my tank, am having issues with my corals, is it the GE II or because this is my first salty tank... IDK? my corals are alive... has been running with this silicone for almost a year now.
