Hi all, I have a 150 watt bird bath heater in my plastic 5 gallon nipple waterer. I want to add ACV for all the associated health benefits, but I'm concerned with the heater's metal interacting with the ACV? It's only been out there for a few weeks and already it's starting to get encrusted with the calcium from our really hard water, which the vinegar would also help with, assuming it doesn't cause problems with other minerals!
The only metal I would use in a acid like ACV is stainless steel. The nipples should be alright but the heater may be a problem. Use another waterer for the ACV to supplement the regular waterer if you feel you have to use ACV before spring. A container that can stand freezing.
