We aren't duplicating indigeonous conditions, outside of people growing Darlingtonia or Sarracenia, etc... in their backyard, near where they normally grow. What I'm getting at is that rain washed away dead material and provides cleansing that we don't in our setups. Dead material, algae, and mold aren't a problem in nature (generally speaking). With ours, we have be more proactive. It's similar to tropical fish and ich or bacterail infections that wipeout fishtanks. It doesn't happen in the Amazon Basin or the ocean. So if fishfood lands on the media, we have to deal with it. If it landed in a bog, it wouldn't be a problem.
