I'm just setting up for using glycol to cool my fermentation. For budget reasons I'm using my old fermentation chamber/chest freezer as my glycol cooler for now. My plan is to use an old aluminum pot in there with about 3 gallons of glycol:water mix at 1:2 parts.
I set the whole thing up with water last week just to test things out. I had planned to replace the water and put the glycol in there today. When I dumped the water there were crystalline deposits on the inside of the pot. I'm fairly certain this is aluminum corrosion. They brushed away pretty easily, but seem to have left the pot with "bumps" on the inside. Not sure if this is remaining salts or if it is pits in the pot.
I was using this pot to try to improve the temperature transfer from the freezer chamber to the glycol. This is an inherent weak spot of this setup. Can anyone tell me if I need to worry about the pot continuing to corrode? Will this affect the performance of the glycol?
Thanks in advance.
