    I've big problem now. My tank water will turn green and it gets greener and greener until like those pond water in the open.

    At first I change 50% of the water but the problem does not go away and keeps coming back so I was forced to change 100% of the water, the water stay clear for 4 days then start to turn green again.

    I was forced to change 100% water, wash the filter but that doesn't help the water has started to turn green again.

    I did not add anything to the water except the Aquamedi kH up powder.

    I'm going crazy over this, feeding is very minimum and I feed once a day only and the fish will finish all the food in less than 10 sec.

    Can someone offer some suggestions? I don't want to change 100% water again.

    Where did you put your tank, is it in the path of direct sunlight?

    Further data, tank is out of the way of direct sunlight.
    it's a 4ft tank with 6 FLs. You suspect too much light?

    hi weileong

    I dont think it is the aquamedic KH up powder as I am using the product without such problems...i dont think it is the lighting problem..as i am running 6 fl tubes in my 4ft tank....could it be cause of your UV shield that you installed onto your lights that may be giving you the problem?

    geo liquid claims to treat everything from algae to fish death
    who knows, maybe if you drink it on a regular basis it might even cure cancer

    try some dapnia first
    buy a bag, dump them inside, and see how it goes

    David,

    Why would it be a problem...... I think the only problem would be the daphnia get eaten by the fishes b4 they get into action to clear the green water

    David,

    The problem already happen before I install the UV shield, remember when I talk to you from my office I have not install the UV shield yet and I've already done 100% water change because of the problem and run out of kH powder.

    Hmm... really bothering me, I'll try not use use UV if possible at all.

    I've tried this Geo liquid but doesn't seems to help. After reading your message I read the instructions again and found that I put in too little so now dose at 1ml to 3 litres, let's wait and see.

    The Daphnia will be gone in less than 10 mins I think, my fishes will finish them. Heheh lots of suggestion and I'll try them.

    I got cloudy water before but they are white, this time it's green. sucks.

    I would add some filter floss in the filter. Half the amount of light for the moment. Change 50% of water every other day till the water clear up. Check the filter floss, rinse it if it turns green.

    Eh not really weileong, if its in the bag, the daphnia should be quite safe...

    Also the other alternative which has been suggested is to introduce duckweed. This help by blocking off some light, and more importantly sucking up excess nutrients.

    Read this Green Water. Its about puting the daphnia in a cloth cage in the tank and placing it near the filter output. Idea is that the algae water gets into the cage but the daphnia are too big to get out, so they don't become the special of the day for yor fishes. Lots of other solutions too.

    Is it a new setup? I had this problem when I started my 3.5 foot. I cut the light to 4 hours, closed all the curtains in the room. Did 50% water change every 2 days. Eventually it went away.

    I've introduce the fog bit and they are growing like mad right now. I'll give the daphnia a try, good suggestion

    Meanwhile have added the correct dosage of Geo liquid so it'll take a while to see the results.

    My tank is almost 2 yrs old I think, if not also 1.5 yrs old, everything very stable until his green water thing strikes, so far no other algae except a bit of green spots here and there but not so much and clean once in a month would be sufficient.

    There are many suggestions from the brothers here and I'll give them all a try. *sign*

    Update:

    Situation is very very bad, yesterday just change 100% water and now water greenish again, a lot of difference from this morning.

    I got some daphnia and made a "breeding tank" for them, I feed part of the output from the filter into this tank. The outlet is filtered with the very fine mesh so they won't get suck out. Will have to wait to see the results.
