[Bern]

It's an alternative product to the aquatic version of Virkon S which is/was an antiviral disinfectant used widely in the livestock industries in the UK.

Virasure is the aquatic version of Victor ( I may have that spelling wrong) a newer antiviral product used in the same way as Virkon S.

There was an article about it in one of our Koi Mags, I'll try and find it.

Like Virkon its primary function is to prevent the spread of viral diseases, but there have been some surprising side-effects like the ones you mention. A friend of mine uses it and he noticed that the protein-foam that used to collect in overhanging plants instead of going into the skimmer disappeared.

On the show circuit Virasure has virtually replaced Virkon S as the disinfectant/sanitizer of choice.
