I have a 100g tank,

My set up consists of  8  4' T8s staggered to cover the 5' ft. I have them 
in canopy about 8-9" off the tank( room for external growth of plants)
After initial setup costs, I bought a case of 25 T8 bulbs for $120 Cdn (over 
3 yrs of lighting).

I am removing 2-4 bulbs and replacing with AH 96W and a 55W CF, to see if I 
can get better penetration to the bottom of the tank.

I use Tom Barr's EI (bulk chemicals cost little, NO2, PO4 and trace , after 
more than 2 yrs, I replaced the NO2, the others will take probaby another 3 
years to empty)

With CO2 the plants, swords, cabomba, and valisneria will grow like mad. The 
problem with ground cover plants is that they will get shaded by the those 
I removed my swords as they dominated over a 1/3 of the tank, cut back the 
Giant Val to one plant and I pull handfuls of Cabomba out weekly.
