I just bought some EE yesterday and poored it into my tank according to directions. Early this morning around 7 AM. I see all my leathers shrivled up. I freaked because I've never seen them that way. ANyway, I looked at the ingedients and saw that it contains Copper EDTA. If I'm not mistaken, Copper is a no no. Leathers seem to be looking a little better now but what gives?
