Algea problem?

My tank is now a very dark green, I can't even see the fish anymore, is this because of my filter, or is it algea? Everytime I clean the tank, it stays clear for a day or two, but then goes back to dark green! Should I get a new filter, and how do I fix this?

Check your phosphate levels and drastically reduce your lighting periods. Cut back on feeding as well, you're only fueling the nutrients even more.

Good luck.

Tanks: 40 gal FW setup, 10 gal Reef tank.

Also try changing the filter media a little more often (Like once a week or so) until it clears. I wouldn't leave the lights on for more than 4 hours until it clears up, then set them to go for 8-10 hours after it clears.
