How uncanny!
Following in from my two recent posts on 2nd and 3rd May (“Refilling your pond with a hose? Beware!” and “How can you use water safely , straight from the tap?”).
Today, I received a call from a distraught goldfish owner who had left their hose on overnight! With 80% mortalities, asking what to do now?
My suggestion was to quickly purchase some anti chlorine from the LFS and some rock salt to dose the pond ASAP!
What a shame as they have had the goldfish for 12+ years! A sad day for everyone involved.
As a fish owner myself, I always have handy, a heap of anti chlorine, a heap of salt and a heap of activated carbon (and other veterinary medicines) on hand to tackle any such incidences. Make sure you too have a stash of these for emergencies.
