Maybe the stainless rod or flat that is bought for welding construction will deteriate faster under those conditions.I am going to continue using my stainless slop trays. Dont know that its kilt anybody by eating off of them.
Bronson,
I'm a stainless using guy too. Until I found the piece of stainless I use now I collected road kill wheel covers. Their large area was good, but I found a larger piece of stainless and trimmed it to fit the bottom of my tank. I have no idea which of the hundreds of stainless alloys any of them are, but I've never seen any yellow in the solution. Maybe chicken little is right but I just don't know... and I'm not very concerned.
No chicken little gloom and doom here, just a word of caution.
Chromates:
"They are carcinogenic. All hexavalent chromium compounds are considered toxic and carcinogenic."
I have no idea how this would effect those who do use stainless in their tanks, I just don't use it. It's really not too hard to pull the expanded metal I do use, and clean it off from time to time.
I wouldn't use stainless myself, just as a precaution. The same as I won't spray paint with a hardener without proper respiration.
