I tried Cabomba once and the buried stem rot on me. It never take roots. 
Recently I get a friend of mine to start a planted tank (he was onto 
Cichlid). He got a few uprooted and floating red Cabomba from the shop 
for free. They grow well for him and root easily. Don't know why but he 
started the 15g tank with Tetra Initial Stick in the subtrate and 30 
watt of Hitachi aquarium FL bulbs.

This is true according to Rataj. It was mentioned in Vallisneria section 
of the Aquarium Plants book. I also found that Sagittaria and certain sp 
of Echinodorus will battle and kill each other if they are touching. My 
E.Maior (Major?) had sustained more damage than I first though. Had to 
throw away almost half of the leaves. One Sag died and the other was 
very close before I replant it further away. It now put out new leaf in 
addition to the 2 tiny leaves that was left. The allelochemical also 
affecting touching E.Quadricostatus but does not seem to affect 
E.Amazonicus (yet?).

This SilverLux is available commercially from 3M. I'm using one in my 
study room. It cost about US$10 for 4' size and is guaranteed for 5 
years. It is parabolic shape and attach to the FL tube though a spring 
holder/clamp. It is almost like having another tube in the room. 
Unfortunately (for me) the 2' size cost only a few cents less and I have 
four tubes on my tank.

Maybe I should use 6 FL tubes with these 3M instead of MH for my soon to 
be 2' deep tank. MH is so hard to find in Penang, Malaysia. Stephen 
Pushak just told me about the heat from MH. Woh!
