Green tank syndrome?

[MarkOne]

My 120L tank has been mature for about 3 weeks now, and has a range of plants..java fern, anubias etc, but the water has looked a little greeny brown for the last 2 weeks or so....I've heard this is because phosphates are too high??

Can someone suggest an option/product which will help to reduce this without affecting the current fish stock?
Thanks!

Do a 40% water change with dechlorinator and then turn the tank lights off and keep the completely dark by covering it with somthing for 2days- algae cannot last long without a light source but large aquarium plants can, as a result the algae will begin to die off but the aquarium plants will be able to hang on. During this time you need to keep your filtration on full blast making sure it creates lots of air bubbles in the water as without the plants making oxygen you are going to need more of it to keep the fish healthy- they will be fine otherwise without the light; doing small daily water changes will also keep the water quality good while the algae dies off .
I've never tried this technique myself as i've never had algae problems but have heard it is very successful by many others.

The green water is somewhat common in bewer tanks. I went through it with 2 different tanks. Water changes won't really do any good other than to make it a little clearer for a short time. I was changing 30% every day and it was getting worse rather than better. I ended up buying a UV Sterilizer and that cleared it in the first tank almost over night. I then used it on the second tanks and documented the progress in this thread.

UV Sterilizers are rather expensive though and the green water will clear up on it's on in a few weeks. As for the fish, don't worry about them as the green water isn't a problem. As long as your ammonia and nitrite are 0, they will be fine. Actually, the green water is quite healthy for them, just not very appealing to look at.

Thanks for the replies guys...I will consider both. The filter has been on full blast since starting. I read somewhere that adding a phosphate remover might help, but I presume as few chemicals added the better?!
