Lookin good!!!
Keep an eye on nitrate with that reactor on there, but it should be darn good at keeping ammonia and nitrite at zero. I wonder if the bio-thingies in there are a knock off of the Kaldnes media. Kaldnes media is supposed to tumble freely in the water which is supposed to make is self-cleaning. I know there are a lot of people who swear by the Kaldnes media on fish only systems - Dan Underwood of Seahorse Source Inc comes to mind.
Kaldnes comes in two sizes, K1 and K3. This is K1 media (I think it is about 3/4" around), is this what yours looks like?
