i was looking at the NP Biopellet but i dont want another reactor! (havent even setup my calcium one yet).
the lawnmower blenny doesnt eat film algea though right? thats my biggest annoyance, the HA is very little and it seems to be going down.
For the carbon, can I run that in my sump? maybe just a large bag of it?
