The following method of fighting bga, I have advocated several times without getting any feed-back on the www. But friends have tried the method with the same success as I have experienced.
TOTAL darkness ( cover completely) for 4 days will do, it will not hurt fish or plants and the most anstonishing is, that the bga does not come back the next day ( or months ). Other algae are not wiped out this way.
