I'm doing DHG in a 10 gal, 2x13w cfl's in a standard hood, excel 3x a week, aquasoil and root tabs and in the past month since I set it up, I can see 30-40 runners starting all over the tank, so in a few months I expect it to fill in the entire tank. Not sure how well it would do without the excel, root tabs or aquasoil though.
20g platy, , 2 x 10g shrimp, 3 x 20g shrimp, 7.5g shrimp and 1 great dane/mastiff puppy.
