Blue Green Algae, fish tank infected with blue green algae Options

[rwalker]

My fish tank is infected with blue green algae (BGA). It gives away a bad fishy smell whenever I physically remove the slimy algae. I check the internet and it says BGA is due to a type of bacteria call cyanobacteria. I guess it all started due to overfeeding

Erythromycin is said to be an effective agent to treat BGA. Some say it is bad to the fish/GB.

Advise is appreciated. And lastly where can I get hold of erythromycin

It is a 2-feet tank running on a sponge filter (no gravel). Yes, you are right, it is not a gold fish tank. My goldfish tank has so far come clean. I guess the goldfish never left any food to waste

The infected tank has about 18 0.8 inches swordtail and some java moss and java fern. With all the hardy plants and fishes the tank is meant to be low maintenance until....

Saw some medication on a fish shop today that claims to be able to get rid of all kinds of algae (including BG). But not sure about its effectiveness.

Advise is appreciated. Thanks.
