patience....and a bottle of Purpleup!! I have that stuff and it works, just wait till your algae blooms are gone then use purple up....i have put in my nano for the past 3 weeks and had coraline growing everywhere...also keep CA and ALK in check, i love that stuff....
yep purpleup does that ! raises calcium and alk and keeps it in check for opt coraline growth...
is it possible to grow some even if you don't dose anything?
