Green Spot Algae

[yeoyl87]

if i am not wrong, green dust algae is a layer of green colour algae growing on your tank wall and it can be easily remove by wiping it away. Green spot algae is a hard green spot growing on your tank wall and the only way to remove it is using a razor blade to scrape it off.

I have a UV, but mines at 5W and its on 24/7. I thought that having a UV of above 11W is not so good for the plants as its destroys certain traces plants need. Can I fit a higher W bulb to the one i have now? Very Ex this one from sam yick...

Sorry no idea, never try, you can ask bro FC aka Freddy

Sorry to pull up an old thread.

Would Burmese sucker (those flat face fellows) help in cleaning up the walls of the tank since they're always sticking against the wall?

[grey_fox]

I had a pair before and they did not really help with any cleaning up of the tank's walls.

Best way to clean up the wall, is of course by yourself.

what is a burmese sucker?

[grey_fox]

Hehe, layman terms, burmese sucker a.k.a burmese hillstream loach.

Opps.... sorry got the name wrong. Its the Borneo sucker I'm referring to. I only know the layman or lfs term. Thanks grey_fox for trying to help me clear the name, is it the same?

Back to the question. Does the Borneo sucker help to eat Green Dust Algae since it always sticks itself on the wall of the tank?

From what I know, they stick to the walls and also prefer fast flowing waters, thus their sleek shape.

If you have GDA, you can invest in a UV filter. This pesky strain will keep coming back over & over again, no matter how much you go about wiping your glass.

Green spot algae is another thing altogether.

Hi Grey Fox,

Regarding GDA, is it cause by unbalance water parameter? i.e. fertilizer, CO2, light etc?

I used to have GSA, but after I start dosing KNO3, KH2PO4 and trace element following EI method, my GSA seem to reduce alot. What took it place is something like "dust" on the glass wall, but I could not confirm it is GDA.

Yup the 'dust' on the tanks' wall is green dust algae. It happened to me way back when I over dosed. What I did was the following.

1. Re-evalute my dosing regime. (cut down on NO3)
2. Cut down my lighting.

Up till now I am not exactly sure of the exact cause of what triggered it but suspect that it could have been that I had too much lighting for my tank with a combination of the overdosing of NO3.

I managed to correct the situation by cutting down on the lightings, from 8 x T5HO to just 6 x T5HO and reducing the amount of NO3 dosage. After a good clean up, the green dust algae disappeared over time.

I overdose my PO4 actually and so far, so good, I've got very little or no green spot algae to deal with.

Thanks for sharing. I will reduce my light from 3 x 24w T5HO to 2 x 24w and see how it turn out. Mine is a 2ft by 1ft tank and I believe 2 x 24w which give me 3watt/gallon is good enough. Before that I have 4.5watt/gallon.
