hey, just looking for some advice, I am fairly new to planed aquariums and have a 20g thats had plants in it for about 5 months. Everything was doing great until recently they started to turn black and die. my lighting is quite low 15W floragrow that runs for 12 hrs/day. But I tryed to choose plants that don't require alot of light. I also use a palnt food supplement 1x per week. I just bought a CO2 unit to see if helps. also is aeration ok in a planted tank?
thanks for the help!
