Thanks all, did a search on what bang mentioned and this is a quote from Sammy awhile back
A very bad case of diatoms or dinoflagellate algae will be brown, greasy, stringy, trap bubbles, and is often mistaken for cyanobacteria. Try looking into that.
It is not greasy looking to me, but it is stringy and traps bubbles. The color issue is throwing me---I have seen diatom color (just a dusting) and cyano color in my tank over the years. What I see now does look more towards the brown side since I just recently noticed a small patch of a different more fushia (sp) algea beside it. I am leaning towards what bang mentioned. The other thing that confuses me is when I clean it up, I can scoot it into one big clump (with some sand) and remove. Now that is why I thought cyano (always heard it peeled off), can a bad dino outbreak be manually removed the same way? So if it is dinos, what to do? Cleanup crew is very low now, but I also still had it when in full force.
Hope this helps.
