Sulfur reactor question.

[Triggerjay]

I have had my reactor up and running for +-5 months. Today I noticed a ditritus buildup? In the bottom of the reactor. Has anyone else running a reactor noticed the same thing? It's running well with an output of 0 nitrates, so I don't feel it would be worth tampering, but wanted to know if it's "typical". Thanks!

It is likely a bacterial mulm, yep it is running as designed..
