I had algae issues in my main tank until went with a 6 hour photo period. I dosed ei and had pressurized co2 with a good substrate and 4wpg of pc light. If found out later that what my problem was my co2 measureing system, got a drop checker and that was fixed. My point is that IMO a shorter photo period will make up for other mistakes and keep algae at bay. I know am going to longer photo periods and seeing more growth. From what I learned most beginners should stay with a short photo period until things are well in control.
