I actually just ordered the same light (fugeray 16") and am a little disconcerned to read that.
Overall though, save for that shaded area, how is the lighting? Enough for solid, compact growth without the need for CO2?
I'd appreciate your feedback, thanks!
I'm not sure if it will produce enough light to promote compact growth with the plants, but so far my experience with this light + pressurized co2 has been positive, my dwarf hairgrass is sending runners already after just a week
I personally think the amount of light you get from 16" fugeray is perfect for a spec V if you're doing a non co2 setup, considering that it's such a small tank.
