Tank maintenance question

[marie]

I bet i have more brown wafer algae then you .
*edit* I think i have just about every pest algae imaginable in the tank...oh well

I tried to think of ways to use vinegar but it would be just as fiddly as using a paring knife to chip it out.

I guess there is no easy fix, as my mother says "It just has to be good old elbow grease"
