The only thing I do is dump a bag into a tub drilled with many holes to help dry that darn wet stuff off. I also leave the lid off. I've never had any issues in the few years that I have used this cypress.
I know a local breeder that has been using it much longer than I have. He has had no problems either.
Do you know the brand/label on the bag by chance? I'm only seeing a cypress blend in stock for my lowes and "blend" in the label makes me a bit skeptical. $3 for a bag would be a bargain if it's pure cypress!
