Hi,

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 
plants.
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.
