Will this metal in the stock tank leech?

[BContos]

I am in the planning stage of a new tank and want to start curing the rock once the aquascape is cemented together. A regular brute trash can won’t work due to the size the aquascape will be. I have one of these stock tanks on hand but am wondering if the brass drain plug will leech into the rock and cause issues? I read that brass takes years to corrode but will tarnish fairly quickly in sea water. Has anyone used one of these before and what was your experience?

I would replace it.

I would replace it.

The plug or the whole stock tank?

When I was building my mixing station on Jan 2021 I used two 120 gallon polyethylene reservoirs for RO and salt water. They come with brass plugs fixed to the body.

since it was the only option I have where I live for this size. I took the chance and used them with no problems until now.

but, I used silicone to cover the inside of the plug with my finger.

I would remove the brass and replace it with a bulkhead fitting.
The tub makes a great sump or holding tank.
Short term, a few months, the brass is fine, imo.

The plug. If you can't find the right thread, drill it out and install a threaded bulkhead that you can seal.

All metal will leech in salt water. Get any metal out and replace with a plastic bulkhead.
