Hi,
I am beginning to have success with my planted tank now, but my so called 'easy' plants are not growing. I have Hygrophila siamensis at the back and it has hardly grown in 3 weeks, and looking a bit pale. I also have a small amount of Salvinia natans at the surface and it is turning brown and dying.
However my glossostigma, lilaeopsis and nymphaea stellata are all growing fast and lush.
4.4g, 2 x 11w compact, DIY CO2, fert substrate, trace dosing only, small frequent water changes, low fish load.
Are the plants experiencing photoinhibition from the high WPG? Ive grown them well in low light tanks.
Or are they indicating that there is no NPK in the tank? I will start dosing TPN+ as soon as I can get hold of some. Will this solve the problem?
Any help much appreciated.
