    Default Filter Media Maintenence & Cycles

    0 Not allowed!
    I have been told before that it is not a good idea to replace your filter media too frequently since doing so can potentially get rid of beneficial bacteria, causing an unintentional cycle. I would just like a bit of clarification on how I should handle this.

    My main filter is an Aquaclear 70. It has three pieces of filter media - a foam brick, an activated carbon filter, and a bag of ceramic BioMax pieces. My question is - how should I handle this? Should I keep all three pieces of my filter media for long periods of time without changing them, or should I regularly replace some of them? I figure the foam brick I can just wash out with old tank water during water changes a few times a month. I'm not sure how I should handle the activated carbon and Biomax media, though.

    I would suggest keeping the sponge and biomax until they start falling apart. I have some sponges and biomax that are now just over two years old and I can not see myself replacing them any time in the near future.

    Carbon should be replaced about once a month. However, carbon is not always required in a filter unless you are wanting to remove something from your water. You could replace your carbon with more biomax
    If you take your time to do the research FIRST, you can successfully set-up and keep ANY type of aquarium with ease.

    Cliff is, as always, right on the money.

    Relative to charcoal (carbon) it has some important uses but for general use, is a total waste of money. That said, always keep some on hand to remove organics like meds when the need arises.

    Bio-filter is THE critical thing a filter does and as Clif says, use the extra volume that the charcoal was using for more bio-chips. Your fish will thank you
    Knowledge is fun(damental)

    A 75 gal with eight Discus, fake plants, and a lot of wood also with sand substrate. Clean up crew is down to just two Sterba's Corys. Filters: continuous new water flow; canister w/UV, in-tank algae scrubber!! Finally, junked the nitrate removal unit from hell.
