looking good If you are having problems with algae then there is an imbalance between your nutrients and your lighting. I am still pretty much a beginner with plants but Byron has given me lots of advice that I have taken to heart. I have 6500K f40t10 lighting on my 75 gallon. I keep the lights on 10 hours a day and dose each week with flourish comprehensive. I do not have any problem with algae and my plants are doing much better since I went to this schedule. I suggest asking Byron.
