Notes: I have this tank on a 13 hour photoperiod which I think is the reason I get as much growth as I do with such low lights. I also have found in my low light tanks that the bubble walls tend to be very helpful because they help maintain the CO2 levels at atmospheric levels. I also tend to slightly overstock my tanks which I think is helpful because it adds fertilizer to the tank for me so I don't have to remember to do it

I also use roots tabs under the heavy root feeders (crypts, sword and a few others)
