IT'd definitely a start! If you get some co2 going in there, then your plants should do great. The stock lighting on biocubes is pretty bright for fresh water. I would suggest switching out the blue bulb for a 6500k bulb. The blue apparently does nothing for the plants (but I have yet to test this myself) I would also add some fast growing plants to suck up the extra nutrients. Since you did a dry start, your substrate is already cycled!
Or you could always take one of the bulbs out.
That's an awesome deal for a bc29! Did it come with the stand?
Good start btw!
EDIT: Nice clowns!
actually, the actinic bulb burnt out... so i am down to just one bulb. i will be replacing it with a 50/50 bulb, just so i can still have some actinic over the tank. actinic isnt for the plants, but it makes the fish's color stand out more, mostly the blues of course. if you have actinic to daylight in a 1:3 ratio, you dont even notice the blue at all.
i've had 60W of light over my 10 gal tank, with no ferts and no CO2, and the plants grow very well and with a monthly overdose of flourish excel, algae is not an issue either.
yes, the stand came with it too.
