Im having cloudy green water in the tank (have been for a few months now) and it just wont go away no matter what i do. Ive tried totally blacking out the tank for days, going for massive water changes, reducing feeding, and reducing lighting, and nothing works. No matter how clear i can get the water, it always goes back to cloudy green. I dont know why this stuff wont go away, i have 1 five inch tiger oscar in a 60 gallon tank. My flitration is a filstar xp3 and i change the pads regularly. I do water changes weekly and run a bare bottom tank to keep it easy to get all of my fish's droppings. I was thinking about getting a diatom filter because i had heard that these would clear the problem right up, does anyone have any advice.

To see the effects of a diatom filter, check out this thread.

Keep in mind, however, that diatom filters will clean up your water only temporarily if conditions in the tank are not improved. In your case, once the algae bloom took place, even partial water changes won't help since the one-celled organisms reporduce so quickly, probably feeding off an excess of nitrate in your water. I would run the diatom filter, then do more frequent water changes to keep any excess nutrients down. Running the filter will act as a "reset" button, allowing you to improve conditions afterwards.

Back in the saddle!

Hi,
To resolve the green water problem, check out this site:
[link=http://www.otocinclus.com/articles/greenwater.html]http://www.otocinclus.com/articles/greenwater.html" style="COLOR: #FF00FF[/link]
If you follow the logic and suggestions, your problem
should resolve itself. Diatom filters will filter the
algae out of the water, but are very expensive, not
designed for 24/7 use, and will clog up within a couple
of hours of use (in your case). A UV system will also
kill off the algae, but these too are expensive to
purchase, and the bulbs must be replaced at 6 month
intervals.

Stick with the "easy way."
