How to clear up greenish water in fishtank

[[email protected]]

I am currently housesitting for someone who has a 50 gallon fishtank.
Just before they left they said they changed part of the fishtank water
as well as cleaned the fishtank. At this time the tank turned a strong
green color where you can barely see the fish. As well, this is a tank
with that has just two oscars. I told her I'd look into what I can do
to fix this problem.
Just to explain up until around 15 years ago I had a 15 gallon
fishtank. As well, for the last 3-4 years I've had a 120 gallon
sal****er fishtank so I am familiar with working with fishtanks. I've
just been out of the loop awhile with freshwater tanks and as well I
know sal****er is a lot different. I'm just looking for any ideas how
I can safely fix this problem. The fish seem to be okay except for
eating a little less. Thank you for any help.

Thanks for your response. They dont' have any plants and it sounds
like what you suggested is the best choice. Is there any danger to the
fish from the algae bloom?

Eh, a little, but not much. There are some oppertunistic
algae and protozoans we normally fijnd with algae but if
your fish aren't sick they should be ok.

The greatest danger is the algae dies, then it rots and
hello Mr. Ammonia!

Oxygen can get quite low at night. Be sure there's plenty of surface
turbulence.
