stop fertilising, light duration shorter..do more water changes.

that's the best way
change your water
if you're despo you can use antibiotics, but be sure to complete the course, or you might get resistant bga
alternatively, you can try the powder that comes in green bottles
kills bga too
but will probably be bad for your fish
tawauboy, have u noticed the water where bga grows is stagnant? Try to get some water movement there.----------------

what is the best method to clear these algae?
tried to remove by hand but comes back after 2-3 days.
----------------
Erm... Control of Algae in a Planted Tank suggests that the low nitrate levels encourages BGA. Maybe you want to treat it by balancing your tank nutrients instead of medicating. I don't know if it'll work but thats the direction I'm taking with my tanks for now.

Why use punctuation? See what a difference it makes:A woman, without her man, is nothing.

actually algae like BBA, BGA r a cause when there is low/no level of certain nutrients in the water
the bga is on quite a lot of the plants.
especially slow growing plants.
i am changing water 50% weekly.
think this started when there was whitespot in my tank.
used medication and that stunted the growth of a lot of plants.
now they are recovering slowly and bga is on them.
i also notice very fine threads about 1.5mm long floating in my tank.
is this the spores or something related to bga?
i only add the trace elements from sera.
have 9 sae.

how much water movement?

I share my story:
After 3 months without success at removing my 65g tank of
Cyanobacteria by regular water changes, I decided to try the
anti-biotic method as a last resort.
I used 3 erythromycin 200mg tablets and ground them up in some water and poured the contents in. That is about half dose of the recommended 200mg / 10 gallons.
I still continue with my weekly water changes and after 2 weeks, I don't get any smell from the water anymore! Whew!
I have quite a heavily planted tank. If there is any death of
bio-filter bacteria, I think any spike in ammonia is absorbed by the plants. So far there's no death to fish and plants remain healthy (except for an outbreak of BBA, I wonder if this is some side effect).
Hope it works for your tank too.

The BBA is probably a side effect as the nutrient balance in your tank was disrupted when you were treating the BGA.

Erthromycin does not kill filter bacteria. It is a myth propagated by mis-informed hobbyist. There are different classifications of bacteria, one of which is the reaction of chemical stains on the bacteria cell walls, known as "Gram Staining". Erythromycin affects gram postitive bacteria and leaves the filter bacteria which are mostly gram negative. I dun think you will be interested in how erythomycin selective affects gram positive bacteria only.----------------

Juggler, what does Diana advocates about BGA (or alage in general)?? Still cannot get my hands on that book.
we are, we are----------------

always good to know more things
i always thought gram-positive meant no cell membrane, but cytoplasm
while gram-negative was cell membrane AND cytoplasmic layer
Long long ago ,some1 mentioned using Maracyn2(antibiotics too)for BGA
Saw it at Wong Loy Kee a few day ago(New stock)
Good Luck
i believe the active ingredient of maracyn 2 is erythromycin----------------

Confirm. Maracyn = erythromycini believe the active ingredient of maracyn 2 is erythromycin

Erythromycin belongs to a class of antibiotics known as "Macrolides" (as opposed to other classes like beta-lactam (e.g. penicillin) and tetracyclin, based on their chemical structure).
It inhibits protein synthesis in the bacteria cell by attaching to the 50S subunit of the bacteria ribosome (got 50S and 30S), thus blocking the release of the tRNA at the P site (peptidyl site, as opposed to the A site). This prevents translocation and therefore inhibiting protein synthesis.
No. gram reaction does not mean one have cell membrane the other dun have. ALL HAVE membrane. Plants, animals, fungus, even you. How else does the cell controls what goes in and out of the cell? Gram + means that the structure of the bacteria cell wall of is able to trap the stain crystal violet and is stained blue. While gram - bacteria, although stained with crystal violet, it is washed off during destain and is stained by counter-stain, usually saffarin (pink). Gram + bacteria have thicker layer of peptidoglycan (carbohydrate which makes up the cell wall, this one you dun have).
So why erythromycin selective in it's mode of action leh? Gram + bacteria cell wall/membrane allows the drug into the cell, while gram - bacteria keep it out, although gram - bacteria's ribosome also affected by erythromycin.
Why humans dun kanna from the drug leh? Simple. Our ribosome is different from those of the bacteria. Ours is 60S and 40S.
Sorry to bore you all to sleep.
very interesting

where got boring
what do you do in RL?
or is this part of your interest?
btw the webby u gave stated BGA is gram-?
how does it work then?
"Maracyn = erythromycin"
I'm keen to try this out,
any idea where I can purchase it?

Gram staining is just a simple method of classifying stuff bacteria.
Given the dynamic structure of the cell wall, it is not surprising to find expections to general given "rules" of antibiotic range based on gram reactions.
I am not sure if science has deciphered this out already yet, but if you are interested, maybe you can dig into it and let us know.
