To all you rodent breeder extraordinaires...

I'm suddenly have an issue with the my watering system getting clogged from some kind of growth. I have a standard waterbucket/tubing/brass valve system....

I've always used a capful of bleach / 5gal of water and I've never had an issue with anything clogging in the several years previous to now....

The clogging agent is white, kind of a snot-like consistency...

Any ideas as to what it is/how I can fix it?

Thanks!

Justin
