Cyanobacteria?

Dont you find using a antibiotics also crashes your biological filter? you kno the one that took you about 30 days to setup?
Using any type of antibiotic like you suggest will do just that kill everything in its path, not just he easily cured cyano.
Also using antibiotics in your tank then doing a water change, introduces antibiotics into the water table creating unkown havoc on the sewer treatment plants.
Definintly dont use antibiotics.
Anyone else on this with me?
