Green cloudy water - help

Postby Walkthelyne on 16 Jun 2015 18:51

Hi all,
Hope ye can help. For about a month now my 120 litre tropical (24 degrees) tank water has gone a cloudy green colour. I used everything from green water cleaner to filter aid, changed filters, anti algae filters etc.
I got the water tested and was told the PH was low at 6 (tap water) so tried using API PH up. No good.
Replacing the water gradually with RO water did clear it for a bit but it gets cloudy again after a few days.
I know I could go for a UV option bit want to minimise cost.
Any advice appreciated as I've lost a lot of fish.
Thanks.

Green water is caused by one cell algae and usually the culprit is ammonia ( maybe a dead fish you haven't seen or rotting plants leaves or tank not properly finished its cycle) and very hard to be shot of it. UV sterilizer is one of the quickest to get rid of it but if you don't want to spend try a complete blackout for three days followed by a large water change, or get some willow twigs ( fresh) about the thickness of pencil and stick them into the substance with tips above water. When the willow puts out roots the algae should disappear and when completely gone then you can take the willow out ( try this as I never done it and am interested how quick it works ;) )

The position of the aquarium being so close to the window could be a factor,especially if it gets direct sunlight which would make the algae issue 100 times worse .

Cheers lads.

I'll try the blackout method....or if I come across a willow tree I'll 'borrow' a few twigs. The window next to the tank doesn't get any direct sunlight during the day and I try to minimise artificial light.
One of my grasses wasn't looking too healthy lately so I think I'll remove that too and see if it helps

get the NT labs algae gone .. worked a treat for me
follow there youtube video for dosing not the package as there are differences

I also done a water change 2 days after and rinsed out the filter media
so all the algae was removed from the system

Great thanks for that. I'll see where the I can get it.
The algae only appears to be in the water, no algae on any of the surfaces.

It is normal for it to be only in the water column
As Dave said it is a single cell algae and too small to
Get trapped in the filter so keeps cycling around the tank

The way the algae gone product works is it binds the algae together
So it is in large enough particles to get stuck in the filter

End product clean water :)
