Aluminum

[Cory]

So my tank cracked and to replace the tank i bought a 350 gallon water tank for horses and cattle that ill use as a pond.

Problem, it has an aluminum reinforced drain valve. Would this be a problem? I siliconed everywhere on the aluminum so that its not in contact with water.

If it is not in contact with the water it will be ok. If the water gets to the aluminum, it will likely heavily corrode.

Heres a pic of the aluminum. Its under the abs screw in valve.

Corroding would be bad. Any good way to permanently seal it?

Maybe i should stuff the hole with some epoxy stick for corals as an added protection?

I looked it up and this is the kind of aluminum:

6061 is a precipitation-hardened aluminum alloy, containing magnesium and silicon as its major alloying elements.

I used a pond liner to be safe
