Making old old galvanised trough safe for drinking
« on: June 01, 2013, 10:39:21 am »
I have got the use of an old (and large) galvanised water trough for my pigs.  It has been sat unused in the corner of a field for the last 6 years or so, full of very green and algae-full water.  I've emptied it out of as much muck as possible but a hard crust remains on the sides, presumably left by the past years of algae.  Does anyone have any experience/advice on bringing such troughs back into action.  Should I be concerned about the crust and any algae (potentially harmful?) left in it?  Any good techniques for clearing the crust without damaging the galvanising?

Don't try to scrape the gunk off of the sides when it is dry ! Refill with water and allow the gunk to soak and soften , then clean off with i stiff brush , but not a wire brush ! A scrubbing brush , plastic or bristle , should do the job .
Don't use anything like washing up liquid in the water if animals can get at the water to drink .
Just allow the hard crust to soak and soften and then plenty of elbow grease should do the job .

Thanks for the advice Rustyme and fifix.  The trough is now soaking but I think it's going to take one heck of a lot of elbow grease: it'll be good for my biceps.  I like the goldfish idea too - we already have them in the water tanks in our veg garden and they do a great job eating the midge larvae.  Sadly these might be our last pigs for a while as we have to move and pigs might not be compatible with our new neighbours, so I won't be goldfish-ing the trough.
