yes, because HC need strong light, low temp, and CO2, but i do not have co2 in office. low Temp work with office air-conditional. the light is not that strong too.
so i make it as emmerse, which it will get co2 from air. it will grow faster. but will need to keep it moisture.
hahha Jason i am still a newbie too... lets learn together
below is the setup of my nano.
Tank Size: 30cm X 17cm X 23cm = around 9L water = 2.25 gallon (not very sure is it 1G : 4L ?)
