Probably would be OK....the actinics only count for 20% or so of their rated wattage, so that would give you 193 useable watts or just under 2 wpg
. You'd be close to the wattage needed for CO2
but might be able to get away without it. On large tanks less light is needed to get useable wpg
than on small tanks.
Not sure about the 12000K bulbs though, now that I think about it. Most people recommend bulbs between 5000-10000K for plants. 12000K may not provide them with much useable light.
