Thanks for the awesome suggestion
But I actually got the coralife for an awesome deal from a guy (with relatively new bulb) and since I am an student, I have to resort to that.
I think it will be within $6-$10 for my bulbs so no biggy. I just didn't want any "significant" rise as that might cause my landlord to shut down my aquarium :P
I moved from regular fluorescent to this and the lighting is just MIND BLOWING. Didn't expect this much change!
