I know I know.....more co2. Honestly, i am not playing that game.

This is very interesting, and it may just answered why sword plants were dying after they were added to my friend's fish only tank. (

A friend has a 125g fish only tank that he keeps mainly cichlids. His nitrate level has always been high in 80-100ppm range and gh/kg both in the 180-200ppm range. After he saw my planted tank, he also planted some a-swords and java ferns to enhance the looks and to reduce nitrate. He has 1.5w/g of lighting, no CO2 and wc every 2-3 weeks.
His swords and java ferns are doing very poorly, yellow leaves wilting away. His nitrate is still in the 80-100 range.

Why can't the plants use the N in the water column? Not enough CO2? Sorry for not staying on this thread.
