So Im in the middle of constructing a corner matten filter for my 20 long axolotl tank. I have heard from dozens of sources that GE1 Windows and Doors Silicone was safe and so I used that to secure the corner guards in place. However, I found a source that says GE has recently added antifungal chemicals to their GE1 without changing the labeling. I also know that GE says their product isnt aquarium safe but I just assumed that is for liability purposes. I really dont want to have to scrape all this off and redo this filter but I will if there is even a chance it could harm Salem. Can someone please confirm whether or not GE1 is truly safe for Axolotls???
