Found a new color is my moss

[bpace96]

I’ve been watching how much moss in growing in my tank and noticed a couple new colors at the top of my tank. I have a 75 gal with one mason tank, a sapphire damsel, and a snowflake eel with a few turbo snails and hermit crabs. Any help is appreciated.

That is cyanobacteria. Increased flow should take care of it. Remove what you can by blowing it off with a turkey baster.
