Tom,

The fungus I had didn't break up by using Biobor fungicide. It was a brown, silicon rubber type substance that blocked the tank strainer. I couldn't find anything that would dissolve the fungus so I had to mechanically clean the strainer with an air gun.

If the fungus plugs up the primary or secondary filters, they will have to be replaced. This frequently happens after using the fungacide so carry spare filters.
