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?
