algae or sponge?

[nycsicktank]

good or bad?

I had to look hard, do you mean the green? The brown? I'd say algae in both cases.

 

[nycsicktank]

sorry, yea color green. oh is it bad?

 

[Grins]

Is it hard? If so it is probably coraline. If it rubs off it is probably micro algae starting to rear it's head.
