Algea bloom

[r1v2c]

over the last 2 days my tank water has been getting prgressively greener... and I don't know what to do. I've alreay done a partial water change, but the color has remained the same.
There is no direct sunlight hitting the tank and I don't really see much left over food when my fish finish eating. Any suggestions ?

How long has the tank been set up? what are your parameters ie nitrite/ammonia/nitrate? How big is the tank? What livestock do you have in there? Do you have some sort of filter running carbon? how long do you leave your lights on each day?

my take (65gal) has been setup for a little over a month with 40 lbs live sand and 75 lbs of live rock. Amonia:0, Nitrate:0.1ppm, Nitrate:don't have a test for it (yet). For now I have 2 ocellaris clowns, a yellow tang, 4 trochus and 2 nass snails, a cleaner and pepp shrimp.
I have a seaclone skimmer and fluval 304 (which include a carbon portion). Finally, I leave my lights on for about 11 hours a day.

Phosphates feed off the light which is partially the problem of your algae bloom. There is nothing harmful woth the algae bloom. My tank went through the same problem when first set up. I was unable to get it under control until I wrapped my tank for 24 hours. I also added Rowaphos to my canister filter and the water was spotless the next day. There is info on the web about wrapping your tank, it needs to be blocked off from all light source and no peeking for 24 hours. With no light the phosphates drop and the algae dies. I'm not sure if there is any controversy to this method but I tried everything else first and nothing worked. I now keep the rowaphos in my canister filter all the time.
Your lights are being kept on way too long for a new tank, they should be on for no more than 6 hours.
