Has anybody noticed an odor after making a custom background? I know I posted something before about noticing a silicone smell after letting my tank cure a long time, but that not really what I'm smelling anymore. This is the first tank I've done a custom background on and it smells different then my other tanks. Does cork have a smell when its wet? This has got to be the dumbest question I've asked yet, but I'm not trying to have dead frogs when I get some in there. Thanks for the help.
