API Erythromycin vs BGA

[smellslikefish]

Today I decided to treat my 2 gallon tank with API E.M.Erythromycin (10 powder packs) for BGA bloom. The instruction tells me to add 1 packet (200mg) for every 10 gallon (38L), so this afternoon I added about 1/5 of a packet into the tank, but I'm not sure if I should add the same amount tomorrow, and how many more days should I continue the treatment? (i.e. should I keep treating for few more days even all the BGA is gone?)

Use this method: http://www.plantedtank.net/forums/1439320-post26.html Personally, I'd add the entire packet the first day and half a packet for the next 5 days as recommended by others. Too small of an amount and you aren't doing much but creating super strains of bacteria.

With all medications you should complete the entire cycle per the instructions, even if the symptoms go away. However, overdosing 5x as the poster above me recommends may be a bit of overkill. In my case dosing nitrates got rid of my BGA.
