Hello,

I have a 60 gal tank, fluval 404 plus under gravel filter with two power
heads. My Amazon Swords are not doing well. Nothing I do seems to help. I
have an aqua glow light on 12 hours a day, temp at about 80 degrees. I
fertilize weekly. Even added a CO2 infuser. Plants continue to turn yellow
and die. Any advice would be appreciated.
Thank You
