I keep having to clean the area in front of the main jet in one of my toilets. There's no problem with the rest of the bowl but almost immediately after cleaning a grunge begins to grow starting at the main jet and moving out from it almost like a liquid slowing draining out.
Picture
Every time I clean it I pour bleach into the bowl and let it sit for
10-15 minutes, but it doesn't prevent this.Before the unclever cracks begin this is not crap, it's some kind of fungus or algae, etc.
