Does this have any pesticides in it that can hurt my fish? I have my old 10 gallon aquarium and already cut out the seal. Just needs to be resealed.
Thanks in advanced!!
The company there is saying it is completely safe AS LONG AS it is already FULLY cured and not partially cured where it could still leach toxins.
So, as long as you are using it on a dry, empty tank, it seems safe to me
Don’t ever cheap out and try to substitute with something this crucial. Yes , this stuff is expensive but buy the stuff the manufacturers use and sell.
By the time you reseal a tank, you have done a lot of work. It isn't easy to do. If you add a product that's toxic, it stays that way. The tank is ruined by it. If you add one that doesn't grip the glass, the work undoes itself fairly quickly.
