You mentioned that your lighting fixture is the Current USA Satellite Freshwater LED+ Fixture. Is it the 24"-36" size?
I have a 30" Finnex Fugeray on my 29g tank and always seem to be fighting bba and green spot algae.
It seems that your lighting has provided your tank with the perfect amount of light without need for pressurized co2.
Your doing a great job!!! Keep up the good work.
Also, what color setting are you using? Is it one of the preset colors?
