Hi everyone!
Recently I set up a 12 L nano tank. I put some Rotala sp. Nanjenshan in it and at the beginning, the stems were straight, growing towards the light. But after a few days, the stems started curling and bending, growing in all kinds of directions - just not the one I wanted, which is straight up towards the light like for instance Rotala rotundifolia. The stems sort of creep a long the sand.
Is this normal or is something wrong with my plants? Can I make the plants stand up straight?
Info on my tank:
12 L
DIY CO2, app. half a litre, the tester shows light green, should be fine. I don't turn it off in the nights.
2 x 20 watts halogen lights, app. 15 cm for water surface
no additional heating but temp. is from 22-28 degrees celcius.
small hanging filter meant for nano tanks, just to create a little motion in the water.
App. 0,4 ml Tropica Aquacare micronutrient every day
Macro is EI (KNO3, KH2PO4, K2SO4)
substrate is sand 1-2mm only
I would really appreciate your help. I've had this problem with this specific plant several times now, and I'm getting tired of the plant which is really sad because I love the starry look of this little Rotala.
Kind regards,
Marya
