The increased algae might be from the absence of oto's but algae will readily use light of any spectrum, if plants aren't growing.

The Sylvania Gro-Lux bulbs are my personal favorite. I like to split a mix of the regular and wide spectrums, though. Between the two, you can't beat the availability of photosynthetic useable radiation (PUR). See the Lumens and PAR thread if you really want to know why.
