High lighting will keep it red but I've no idea how to keep it short. Mine grows like a monster !

My light is very strong but no sign of red leave yet. Mine grow light 4cm to 7cm in length. My current lighting is 6hours only. The last time i increase to 8 hours, I see a lot of green dust algae on the glass..
My lighting is only 2x18W FL tubes on 2 footer & I have a mixture of green & red leaves. Like any other Echinodorus species, this is a heavy root feeder. You will need to have a rich/fertile substrate for them to grow well.

My experience is have to trim many times before they started growing short. The pre-condition for this to happen tho are:
1. Strong light of 3.5 to 4 wpg.
2. Good CO2 ard 30 ppm.
3. High level NPK and trace elements (Try ADA Lights + ADA Step + Brighty K)
4. High level of Iron (Try ADA ECA)
Can also try to put in Ferka Rosetta or Wondergro root+. However, with such a configuration, they grow very fast and every 2 weeks have to trim to keep short. Alot of effort
On my 35g my previous lighting was at 3.8wpg of CFL's. With that much light the tenellus had red leaves and stayed below 3 inches. I recently changed to 3.1wpg of PL's. Now the length of the leaves is probably 2X or even 3X longer and the redness was gone. I dose via EI with pressurized CO2. Substrate is just plain gravel.
