Daylight is not good, generally: you'll end up with a cyanobacterial bloom, and algae problems. Keep the lighting to what you can time and control the spectrum of...
The algae is due to nutrients in the tank, and often to nutrients in the rock that will leach out slowly over time. It took mine two YEARS to be done with that phase. Meanwhile fix everything you can fix BEFORE fluconazole, and it'll guarantee that works well when you get down to using it. Not fixing means dubious results.
If it's any consolation most tanks go through this. Patience, and getting the water into good shape are key.
