Cyanobacteria problems...help

[Reef_kid]

cyanobacteria generaly grows when there is an excess of nutrients and organic waste.
treating a tank with erythomycin is good for killing bacteria however all that dead bacteria will provide more nutrients for bacteria to grow if its not removed. best way to do this is run active carbon after a treatment and increase skimming if possible.

there are also chemicals such as Poly-ox which will clump organics and waste together
which makes them easy to remove in filters.

increase flow and removing organic wastes are one of the best way to get rid of cyano.
