I have a few questions. I have been keeping cichlids for a few years, but have had zero success with planted tanks. I am planning on creating a planted tank with a 60 gallon tank I am recieving from a friend. I have already ordered a 216 watt T5HO unit. I am planning on starting with low light plants. Maybe a few swords. Is this too much light for them? Should I invest in a pressurized co2 system? If so, what would be a good system for this tank? The tank comes with sand. Should I use the sand, or should I invest in a sustrate. Please bless me with your guidance.
