				Hi, I'm new to the forum and want to let you know I think this is a great site. it has helped me out a great deal. I have a question about my 5 gallon, low light java moss and cherry red shrimp tank. Since it's such low light, I don't really plan on using ferts all that much, if at all, but what about using activated carbon in the filter? Bad idea or not. I was thinking it might be good for the shrimp. Any ideas? Thanks,
John

				imo, activated carbon isn't needed, but adding it won't be detrimental to the shrimp.  i run only an air-driven sponge filter and have had no hiccups.  it's up to u.

				Years ago I kept a goldfish-only tank.  Goldfish are quite dirty when comparing with tetra or shrimp.  Sometimes the water was cloudy.  But it became crystal clear overnight after I had added a bag of activated carbon in the filter.  That's my observation.  But I don't know anything about its scientific composition.
