Arghhh I've never used silicone in a tank before with plants still in it. Usually the tank is empty when I start my silicone work. I was fixing my pond area because it started leaking a few weeks ago. I did not tear apart the entire tank, I just didn't have the patience for that right now. Mistake. The fumes from the silicone has killed all my plants in the tank.The pond area is going to be awesome, but a majority of the leaves on my plants are dead and some of the plants are completely dead. I am very frustrated but I wanted to let people know so that they do not make the same mistake.
What I used - Amazon.com: Silicone 3 oz.: Pet Supplies
