Bright Flourescent Yellow Slime

[wmcinnes]

I have been getting a bright yellow slime on my sand bed and, in places, on my rocks! What is it and how do I get rid of it!

It looks more green in the pictures that it does to the naked eye.

Possibly Cyano. Looks like some red in the corner too

my tank went through a phase with this stuff and everyone claimed it was cyno. also tried to sell me chemi clean. instead i bought a yellow eye kole and it took care of it.

You know Wayne, I have the same thing in my tank. It's only been there a few days. I wonder if its something thats in our water?

[wmcinnes]

Could be, but I use RO water only!

I think im going to treat it as if it is cyano and see what happens.
