Mixing bin has become a nitrate factory.

What test did you use to test it?

Hanna marine ammonia.

Hanna marine ammonia.

Thats one I do not have. I dont feel for most of what I do testing ammonia is that important. But maybe I should rethink that.

Had a similar problem years ago. Replaced the gray can with a white food grade can. Problem solved. A local reefer advised me the non food grade containers leach causing nitrates.

I’m not convinced that is true for Brute cans. I cannot really see what would be in polyethylene that would leach out and boost nitrate. FWIW, I have used more than a dozen of them.
