I don't have any definitive answers for you but....
How heavy is your tank planted? Like a thick jungle/dutch tank or just like 6-7 plants? Got a pic? You might want to throw in a bunch of fast growing stem plants to outcompete the algae, then later swap out the stems w/ something else you like
Are you dosing fertilizers? Dry "macro" ferts? I'm assuming you are probably doing "micro" ferts (trace minerals etc) from Kent or etc?
You have a ton of lighting, 4.72wpg! I think there are a lot of poeple that go with such high-lighting setups (most do not), but you have to realize if you are going such high-light, then the margin for error is very small. Planted tanks are about a "balance" between fish load=plant load=co2=fertilizers=light. Lower light gives you more wiggle room to have an inbalance somewhere...higher light will pummel you if you don't have it just right. I don't think many folks go w/ 4.7wpg, and for 11 hours a day, unless you have a TON of plants to eat up the light. I could be wrong here, but I think you need to at a minimum scale back your lighting hours, not have such high watts on 11 hours, maybe only a few hours w/ the full 4.7wpg? You'll have to see what others say.
The basic theory with algae, is that you want the plants to "out compete" the algae. To do this, you have to have the nutients they need (co2, light, fertilizers) so as not to "limit" growth. You aren't doing macro ferts it doesn't look like, so this could be part of your problem...
Go to the "algae" sub-section of this forum
, you'll find other links that explain how to deal w/ specific algae's. Also do a "search" for "hair algae"
, I just did a quick search for "hair algae" (if that is what you have, might also be "clad" or etc), and most folks recommend a) manually removing it 2-3x week, b) getting amano shrimp and maybe SAE's to eat it, c) spot treating with excel (get a plastic syringe, turn off your filter, apply the proper excel dose (5ml) just specifically on the affected area (not onto moss will ruin moss), turn pump back on 15 minutes later. You'll have to search around and make sure that's good advice, but seems about right...
Most algae's do not thrive in the "same" parameters that most plants do (yes, algae's are plants I know...). Many algae's thrive in lower Co2 (BBA) etc...and many algaes seem to thrive when the water parameters are not "consistent." ie, fluctuations in co2: it takes plants time to adjust to different Co2/nutrient conditions, producing enzymes (something like that?) etc to adjust..but the algae being so simple can adjust and thrive very quickly.
So, long story short, you need to provide a consistent and ideal environment for your plants. You should look into "EI" estimative index it is what most folks do here. Do a search for "what is estimative index". That is how most people handle dosing macro ferts in a manner not to build up excessive amounts of ferts, without relying on cheap test kits to tell you where the No3 levels etc are at. You can get dry ferts from www.rexgrigg.com
pretty cheap combo pack.
