I bought this barrel of bleach 2 weeks ago and it has been stored in my garage with the caps in place. I cleaned 2 houses

from this drum and the only thing that went in this tank was a hose from a transfer pump. I have never seen this before.

I pumped bleach from it today and the bleach is red. The bleach was purchased and pumped into a reputable companies drum

and as I said before the bleach was working but it was not this color. Have I lost this drum of bleach? Please help!
