OMG IT'S CLADO!!! AHHHHHH RUN!!!
:hihi: sorry, personal feelings about clado. Anyhow, you got CO2 and good lights in the tank? Clado really effects you most in that it grows just like a plant would, so by the time you're able to use a technique to kill clado, you're killing your plants as well. They're tough.
However, they mostly only affect you if you're growing foreground plants like hc, ug and oh...let's not forget dwarf hairgrass :frown:...and plants that clump together like moss, riccia.
They also like attaching themselves to driftwood and grow from the substrate up, hence why they affect dwarf hairgrass a lot. If only they glowed or something...oh well.
They're not bad for shrimps or anything and they can be nice if you know how to control them.
