how old is your system. if its still new its natural it will pass when your tank settles. if your tank is settled down then it can be direct light on the tank or the room is bright. check your phosphate levels as well and nitrates.

I would normally advice you to reduce the amount of light but since you only have it on 4-5 hours a day that is not the problem .Do the tanks gets any indirect sunlight?
Also you are not over feeding so that can’t be the issue either. Have you tried any products against algae? This site is good :http://www.algone.com/ it has stuff for salt and fresh water tanks and it will make your water clear. I used it on my fresh water tank once, it didn’t hurt plants or anything.

Green water is a form of plaktonic algae and it is from excessive nutrients and excessive light. The green is chlorophyll so by definition, there is light sustaining those organisms.
The excessive nutrients can be high nitrates (common in established tanks, need to deeply vacuum the gravel), high phosphates, high dissolved proteins (you need a skimmer), and high silicates (need a special filter media– very common in the spring if you’re using tap water and not RO for your tank).
Here’s a good link for you:

I’m assuming that if you have a marine tank that you have a good independent fish store selling those fish to you, so take a water sample in and go talk with them.
You can get rid of the green water now by doing as much of a water change as your fish can tolerate and then wrap your tank in blankets that totally block out the light for three days. No peeking! The lack of light should clear the water, but unless you resolve the other issues, you’ll be right back where you started. Avoid dumping chemicals in there because they all come with their own problems, and don’t address the root problems.
You didn’t mention your water parameters so I’m assuming that you aren’t testing? You should know what your nitrates are, because they’re probably pretty high. Tanks should have nitrates under 20 ppm, and since plants really like to have nitrates over 20, excessive algae is always a sign of high nitrates.
Good luck and happy fish keeping!
