i noticed on my old 11.4g that after i filled it, the hc seemed to take off and thrive much more than it did when it was dry starting. right now my photo period is 12hrs, so i hope it doesn't trip out after i fill it, crank the co2, and reduce the light to a 5-6 hour photo period.
thanks again, and i will be watching this thread for updates!
Many don't reduce the photoperiod so it's not something you have to do. I didn't even learn that from anyone else, my dry starts were hit or miss with algae issues so it's just something I decided to try, it worked a few times, kept doing it. Cranking the CO2 will be helpful regardless though.
