    I did a site search and couldn’t find an answer. I am using an under gravel filter and it came with small charcoal filters on the lift tubes. How often should they be changed and do I even need them. I have always used under gravel filters and they never had these before.

    Its a newer thing. The charcoal lasts about a month till its no longer effective. Do you need it, not really.

    Take them out, they’re just a gimmick and will reduce the efficiency of the filters. Also it’s now known that carbon is not a good idea in an aquarium. It has been implicated as a cause in various diseases...

    At the risk of dragging this off topic I have to ask

    Such as?

    Carbon produces microscopic dust particles that get into the sensory pores of the lateral line. This has been shown to be a contributing factor in HLLE (Head and Lateral Line Erosion) and it’s related condition HITH (Hole in the Head).

    Agreed.

    I remember reading a paper, possibly a scientific paper, on it being the potential cause of hole in the head disease. I'm honestly not sure what to think.

    Thanks for the info. I don’t have any fish in there yet. My glass top, lights and pump are coming today and plants tomorrow. Will remove them ASAP.
