Thanks for the input guys,fyi I have a 1yo 10 gallon tank planted with Riccia and Java Moss and they just thriving!! The temp is around 26C with a DC fan and 3x11W PL light w/o base subt except clay balls.

I found out one way to cut corner on lighting to promote plants growth.
Previously I only use 2x11W PL on my 10 gall, Riccia was doin ok but not very vigorous..later installed a 11W PL table lamp positioned OUTSIDE tilt at 45 deg facing the front of the tank (fish seems ok with it!!).
Results...higher intensity without introducing extra heat and the plants just LOVING IT..even with very low Co2 concentration...
But it's a different story when it comes to 120gallon..tough job man,i have to use several chairs just to work around my tank..(3ft tall cabinet)!!

The reason I chose FL over PL was due to it's popularity and cost. If I were to install PL lamps, I'll need about 10 tubes for optimum
light...very expensive lar b'cos im cheapskate..hhehhe !!!

So far found one solution for higher light concentration, install
one 20W enegry saving bulb on to the T-4 lighting strip and hopefully it'll improve.
I went to Aqua Marine Fresh last week.. and the lady boss told me nothing beats Arcadia lamps even Azoo dont stand a chance wor...Anyone try this brand before??

I have an idea about building a MH light strip after I stumble across a MH bulb at the elec shop sold for RM80...wonder would it be practical design:
1x150 W Double-end MH bulb
1x Reflector RM19
2x 20PL Bulb =RM50
2x DC Fans

Any feedback!!!
