fungus in tank system

I am having a big problem with fungus in the tanks system I use.  I 
have shut off the unoccupied tanks to avoid contamination in them. 
The problem exists in the tanks with the fish.  There is growth 
behind the plates in the back of the tank.  These plates are 
designed to keep the fish from flowing out with the water, but allow 
waste etc to flow out underneath it.  The growth does seem to 
focus/accumulate around the area at the back of the tank where 
the waste and dirty water flow under the plate. It is white in color 
and appears in siphonous clumps when observed under a 
dissecting microscope. I have heard that methylene blue can be 
used to eliminate the fungus.  I am unsure of the concentration to 
use and the side effects of this (both good and bad, other than 
eliminating the fungus). If anyone has any suggestions or ideas, 
they would be greatly appreciated!  thank you!  

Sincerely, Christina Quasarano
