Check out the msds for it. This is info I got from someone who works at seachem. I researched it due a bad rash I got from some of my excel getting on my hand.
Don't worry, I read the MSDS when I ordered it. I use the 25% stuff from JT Baker
I'm surprised it is used in embalming; I knew it was used in tissue fixation and electron microscopy. I would suppose it'd used in embalming when mixed with formaldehyde.
The things you learn in this hobby
Back to the original topic though; yes, glutaraldehyde can be toxic to more sensitive plants (Vallisneria
spp. comes to mind immediately), but if it is dosed according to Seachem's directions, I have never had problems with it.
