I have another post on the bacteria bloom I have experienced .Irwin my 10 gallon with one happy betta a d four happy cory's, filtered heated etc. I was told it was new tank syndrome from my too much cleaning etc and to wait it out.in ever overfeed either. As I wait it out knave notice an increase in green algae. I am wondering if me replacing the incandescent bulbs 15 watts each) with the 10 watt fluorescents could cause this.they are Ito able brighter and much nicer looking but could this causetgebloom and bacteria growth? Another person told me to put adark towel over it for several days. It's driving me nuts...every advice from doing partials, using cycle, covering it and just plain waiting it out. I am tempted tikes the gravel and filter remove all the water and start it as a new tank using e cycle and bacteria that are in the stones and filter since it is 30 days old. Opinions? Dragon flywas especially helpful previously to me maybe your getting this message Roland might advise.
