HI, does anybody knows how to remove algae that made the water green? Thanx
u mean the water turn green color or the wall of the tank is green?
for green water, I think it change water more freq, like 1/3 every week
for green wall, reduce the ON time of light, scape away the algae, buy more algae eater fish like otto or shrimps, prune your plants
anyone got any better suggestion []
It the water that is green... From what I had observed, it getting greener as the days passed. The best part is that plants are not bubbling or growing. The only ones that grow is java moss.. haiz...
haizz...sad to say bro..u got the dreaded green water algae.do a search on how to cure this.
I only experience green water once when I put very strong lights over a small tank with few plants, plus liquid fertilisation.
I would first suggest stopping fertilisation, or lowering the lights and with water changes.
See http://www.aquaticscape.com/articles...htm#greenwater for more info.

Did you by any chance washed the filter clean?
If you've learnt, teach, if you have, give.
Don't walk behind me as I might not lead, don't walk in front of me as I might not follow. Walk beside me, as my friend.

Hi...
Maybe your filter is not working well.
Check your ammonia and nitrate levels...
Its usually due to too much plants nutrients in the water.
How often you dose your liquid fertilizers?
Green water is very good food for fish fries.....
Maybe I should stop putting liquid fertiliser and change water.... haiz..
Adopt strategies - water change, balance bio/plant load, good CO2 and nutrients (NPK and TE, where N=NO3-N) for good plant growth, establish the biological filtration in your filter and on the substrates, take advantage of aerial growth...etc - that will lower your NH3/NH4.----------------

If you are staying near Hougang, pop by 23 Simon Road. There's a LFS which I just bought a pack of daphina yesterday. They eat the algae.
It is also near to the Kovan MRT station.
-Maybe I should give a overview of my 2 ft tank, so that i can get better solution.
-My gravel is 2.5 Inch tall with a small pack of substrate fertiliser (No brand one).
-A small 5W internal filter wich is connected to a 3 bio ball reactor. (with co2 of course)
-Currently I am using CR 55watt lighting (Have just
bought the tube to both white)
-Temperature is normally 27-30.
-Liquid fertiliser that I use is JBL and FLORA NUTRIMENT.
Plants that I have is glosso, hair grass, java moss.
Glosso had been there for 3 mths, but is not spreading.
New leaves appear, old leaves wither immediately.
Hair grass (1mth old), result also same as glosso.
Only java moss is growing!! The only bubbles that I see in the tank is CO2!!!
Since they are not growing well, I would assume fertiliser fault. Every week after water change, I will drop a capful of liquild fertiliser. Haiz...
You didn't mention fish, can I assume you have none yet?
Your plants are not growing. Something is impeding their growth. Get test kits that check pH, NO3 and PO4. Use your pH kit for CO2 measurement recommended by BC. Make sure your tank has NO3 and PO4 too. Most fertilisers provides only trace elements but not macros. K is something you can't measure so you just have to dose weekly.
Most of the people use blackout method to get rid of green water (I never tried before).
Either you done the blackout or not, you still need fast growing plants, mostly hygrophila (spelling?), bacopa etc. Plant a lot of it. This might disturb your layout, but get rid of the green water by healthy plants first. You will need few weeks to clear the green water.
I think other forumer will address nutrient issues to you.
Cheers
hmmmm.. sounds like this happened when you dosed with the liquid fert. How old is your setup? Suggest your fert should be stopped immediately and follow the recomendations above.
Used to have hygrophila difformis as nutrient sinker. Since it grew fast and sent out extensive roots, I tied it to a rubber suction cup and stuck it onto the glass. When the lower stems grew ugly, just trimmed it and re-tied and re-stuck.
That way didn't have to disturb the layout or uproot at all.

The setup is abt 3mth old. With a few fishes inside (abt 6). Current, I have stopped adding liquid feriltiser and made abt 1/3 water change. I think I can't use black out method cos I believe those plants will die faster than the algae. Hmm... It seemed easy to setup "alage tank" than planted tank..
base on what i have experience, it is likely due to an inbalance somewhere. it is important to kill off ALL the GW algae, else they keep haunting you (it haunted me for 3 long months).
Inbalance of lights and nutrients can cause GW, while ammonia spike can cause it too. Like i mentioned before, try to lay your hands on some daphina. it works like a charm to me, simply because it clear up my water almost overnite and a pack just cost 50 cents.
what i did is to turn off my canister filter, pour away the smelly water that contain daphina (using wife's stocking as a net), and dump everything into my tank. use a small power head to provide some water circulation. you fishes will eat the daphina, but one pack contain more then enough daphina for my 30 fishes tank in a 20G tank. next morning wake up and turn on the light, got a shock when I finally see clear water after 3 long months.
PS. Blackout method might work for other but for me it just didn't work twice. In the end I kill some glosso instead.
kinda agree with daz on this.i tried blackout the otehr time.haunted me for abt 2 weeks.decide to try daphnia although quite sceptical abt it.but then...tried oredi...phew...not bad...clears...although abit greenish.but i believe they ate most of the "algae".
I'm surprised goondoo didn't reply to this thread and advise using of UV sterilizer.
a side note: when u introduce daphina into your tank including the water.. u might be at risk in introducing tons of bacteria/parasite. anyone knows how they cultivate daphina?
totally agree with Simon on the last point. The water kind of stink, smell like some drain water.
thus i drain out the water before introducing the daphina, hoping to reduce the risk involved.
