I was just wondering if anyone out there had any ways of keeping water from going bad. I have several 55 gallon barrels as well as open water troughs that after a while, begin to get green and sticky with algae and bubbles as the water begins to accumulate gunk. I know this is a normal reaction to sunlight but even when I cover the things, with tarps or other materials, I can't stop the growth. In the army, we used some iodine solution to purify water before we drank it and obviously, pools use low concentrations of chlorine. Is there any low tech methods folks out there use before I resort to something else?
In organic agriculture, we use Hydrogen Peroxide to cleanse things instead of bleach and doses are used in water for purification etc. This would keep the water clean and is healthful for the animals. I am unsure of the doses, but maybe do a search using the term organic in the title and something should pop up.
I use small mineral blocks (they fit in the palm of your hand)in all stock troughs that contain trace elements of zinc, copper, cobalt etc, so they act as a mineral supplement for the animals as well as keeping the troughs clean. I'm sure they'd be available in the US as well as here in NZ ?
