ggMing,
Very nice set up. I wish I can have the same in my house....
Mind to share how much you have spent on this setup and the setup specification? Eg the cost of your tank, the sand(ADA?), the plants, CO2, lighting, chiller/heater, filter system, fertiliser etc.
I like the plant on the driftwood. Do you tie them up yourself or it is ready made from LFS? Hope you could share more info....
