Brown and slimy? it could be dinoflagellates. If you have access or know someone with a microscope, take a bit of it and look at it under the microscope. It's the only way to really be sure.
cyano looks like little strain of vegetation, whereas dino looks like a bunch of little creaters oval in shape.
It is very important to properly ID the algae and only a microscope can do it properly, because the treatment is different.
For dino, raising the PH to 8.4 or 8.5 will take care of it, also putting ferric oxide will help for both cyano and dino. The PH tric will not work for the cyano.
