I have a 150 gallon galvanized stock tank. Have had it for 6 years. Have had fish die off at a rate of a couple a year. Did not realize about zinc toxicity. I used two part epoxy pond paint to coat the inside. Has anyone had luck with this?
Not sure what tray you mean, but if the rain is able to hit the galvanizing and splash or spill into the pond, that probably wouldn't be good.Seems like a solid plan to me. Does the top metal tray holding the plants need a coat as well?
