Yup those are them for sure just black.
So far everything seems pretty stable
Well, that's cool. I am very interested to see how they work for you in the long run. They shouldn't build up nitrate as much as bioballs do because they should be self-cleaning. Some of the reason bioballs create so much nitrate is because they trap so much crap in them which keeps the crap from getting to the skimmer where it can be removed instead of breaking down. Using filter socks on the overflows to remove a bunch of the solids from the water as it enters the sump will also help keep that crap out of the media. Are you using filter socks? Imo they are a "must have" on a FOWLR, and often a very good option for reef tanks too.
That Kaldnes media is $50 per gallon. I imagine that reactor was not cheap! It better work!
