Google translated the Title as "BGA at Work" i don't know if it something else or i am hijacking the thread but any way if BGA is at work then,
1)Buy hydrogen peroxide from any drug store (15 baht ) , and follow this video <a href="http://www.youtube.com/v/e3RtpttxIsg" target="_blank">http://www.youtube.com/v/e3RtpttxIsg</a>
fixing the root cause of BGA (one or multiple solutions )
a)Clean the filter , make a 50 % water change every 3 days up 10 days
b)check nitrate levels if less , then add nitrates , BGA could be a result of miss balance of nitrates and phosphates (15 ppm of nitrates should be good enough to keep away BGA )
c )Reduce the light, too much light may cause BGA , or if bulbs are old then change the bulbs
e) increase Co2 level in water , less Co2 is the root cause for all types of Algae's
e)if nothing works then buy antibiotics tablet "erythromycin 250 mg " from any drug store , will cost you 60 baht for 10 tablets (not recommended to use any other antibiotics then erythromycin , erythromycin is aquarium safe, it doesn't kills nitrifying bacteria's and will not reset the biological cycle, plants fishes, yamoto shrimps are not affected ,but i don't know about other shrimps, and moss )
Dose 1 tablet (250 mg) for every 30 liter of water, change 50% water after 24 hours , repeat the same dose for 4 days, with water changes, 5th day make 80% water change, and add lot of nitrates to water , this should work
Remember once you get BGA in the tank they are hard to go 100% , but maintaining a good water quality and good amount of nitrates, it can be easily controlled, so be prepared,

here is Antibiotics i got 2 years back from the drug shop on 2nd floor near food court at JJ plaza , for second time i got it from drug store in sukhumvit soi 15 i guess almost all mom and pop drug stores holds its , don't try watsons they don't have it why erythromycin ? follow the search query https://www.google.co.th/search?q=erythromycin+for+BGA NOTE: Treating antibiotics will kill the BGA, but it will not fix root cause, you have to look into root cause and fix it or else within a month or two BGA will show up again, more you treat them with antibiotics more they will become resistance to antibiotics and you need to keep on increasing the dose ,
