I need to source some disinfectant for my equipment and was thinking Virkon S , is it the same as the what they use on farms or is there a special forumla for aquatics ?
Virkon for aquatics is different for aquatic use - less strength than the farm version -But if you are not adding directly to the pond which the virkon aquatic tabs were for then it shouldn't matter as it will never come into direct contact with fish. Use the farm version for sterilising then just rinse
