[dropdowntank]

I need to glue a a small piece of plastic (from overfill) in the tank that broke. Which glue is waterproof (the tank is empty now) and safe to use for inside the tank?

Silicone?

 

[dropdowntank]

Im assuming its non toxic in small amounts?
Its a very finite small piece so I was wondering if Crazy glue is ok because prob easier to work with for this small area?

crazy/super glue should work fine. It is used to mount coral frags.

Epoxy

loctite superglue, get the jel form so its easier to use and it cures underwater

I have to agree superglue is the easiest with the fastest cure time. It does break down over time however so keep in mind this may not be a completely permanent solution. A small amount of silicone would last much longer.

A two part marine epoxy sets in seconds and once cured is completely inert. Will last forever as well.
