Forgot what someone called it, but there is a large sponge like thing that covers about 25-30% of one of my rocks (a 5-7lb rock).
It has three clear tube like openings to filter water with. It is brownish/yellowish/ whitish
I never remove the rock from the water... but the sponge could get air via trapped bubbles from water changes, etc.
The queston is... can even a little die off from the "sponge" cause my NitrAtes to stay high? (among other factors, I know).
If I move the rock some of the sponge stuff comes off and floates around. I want to take the rock out and scrub the sponge off.
What do you think?
