I've had a 10g sump under my 36G bowfront for over a year now and I haven't been able to really make use of it. In the first chamber, I have a filter sock and a skimmer. In the last chamber, I have the return pump and a MJ1200 pump for a GFO
reactor. The middle chamber is my problem
I've tried putting chaeto in there four times and the chaeto always ends up dying. I have a nice large 6500K light, and decent water flow. The middle chamber is about the same size as the other two combined. This last month as the chaeto slowly died out, I've been slowly seeing more cyano
. I'm thinking it's because the dead material is leaking nutrient back into the tank.
My nutrient levels have always been in check, Nitrates = 0 (API and Red Sea kits) and the phosphates are about 0.05 (Hanna). I also have a light bioload, 2 small clowns, a firefish, YWG with shrimp and a CUC.
So if the Chaeto is dying cause it's starving, what do I put in the middle chamber? thanks
