The four 40 watt tubes should put out enough light for better growth than
that!  Before adding more light I would recommend you try adding chelated
iron (Dupla drops, or one of the many other versions  discussed on this
mailing list). Since you have under gravel filtration, the roots of the
aquatic plants are in aerobic condtions and iron compounds will all be
quite insoluble.  You mentioned you were adding Tetra Florapride, Tetra
Initial sticks and Tetra Crypto.  I am not familiar with these products,
and one or more of them may contain iron, but before you spend a lot of
money on more lights or another CO2 injector, make sure that you have
enough soluble (chelated) iron in your water.  From what I have seen on
this mailing list, successful growers who have UGF maintain levels in the
range of 0.1 to 0.5 PPM.

Good luck!

If you are using sodium borate to adjust the pH, you might get boron
poisoning.  Borate is a necessary trace element, but in higher
concentrations it becomes a good preservative, i.e. poisonous to living
