Im going to experiment with a set of eBay bulbs just to see what $30 for 4x54w bulbs gets you... I already have an ATI Blue+ and Fiji Purple that I'm gonna keep in my Tek Light but I wanna get 4 new bulbs and this seller on eBay has an outrageously good feedback score..!! Besides "do you trust eBay" or "they suck cuz they're $30" does anyone have any feedback on why these lights for $30 wouldn't be sufficient enough to run a reef tank..?? I've read other threads where people vouch for this TopDogSeller and say their bulbs are fine.. Anyhow, I want a blue'r look to my tank but would like some growth as well so If I were to go with a specific combo of any 4 from that seller, what would be recommended..?? 4x460nm bulbs to run along my Blue + and Purple maybe..?? Thanks in advance and please keep any negative thoughts or comments out of here, this isn't the place for all that nonsense..
