The water in my water butt is coming out very frothy - audibly fizzing
and with a "head" that takes 15-20 seconds to clear from a watering
can filled from it. What's left is clear and has no detectable colour
or smell.

This only happened since we had the outside of our hose decorated and
new guttering put in.

I can't see how any paint could be doing this (they used proper
acrylic outdoor stuff).

I was wondering if the new guttering or any sealing material might be
to blame.

If you know, please let me know why you think this is happening. More
importantly, should I stop using the water until it clears, or is it
alright to put on plants that I am going to eat?


Sorry..should have thought a bit more about the Subject Title for this
really. Oh well.
