    I'm not sure I explained myself correctly... the bio-max has been in the filter with the old media for two days, but it is in the filter to stay. The old media will ultimately be replaced with the new filter pads, but there is no room in the filter to fit the old media and the new filter pads plus the bio-max at the same time... so, I have two choices:

    Wait until the bio-max is seeded by the old filter media and...

    1. Leave the old filter media in the filter while I soak the new pads in the tank, or;
    2. Replace the old filter media in the filter with the new pads and soak the old filter media in the tank while the new pads seed from the bio-max.

    Am I making sense?

    sure, you've made sense all along.

    Once the bio-max is seeded with bb, I would not worry about the filter pads being seeded. Yes, they do act as bio-media, but I personally do not depend on the sponge to act as my biomedia. I wash filter pads under the tap all the time, I do not worry about the bb on them. The substrate and the bio-max is the main thing, and these are what I don't risk having exposed to chlorine and such.

    So my own two cents remains the same - let the bio-max seed for a couple weeks, then just discard the old cartridge and install the new pads. Better yet of course is to have two filters running, and clean them on alternating weeks, so you never have to worry about your bb at all.

    Sounds good. Do you ever clean your bio-max bag in tank water during changes? Also, do you ever change your bio-max? I have read that some people keep them in for years in spite of the manufacturer's suggestion that they be changed out every few months.

    Also, do you ever change your bio-max? Nope, [And BTW, Much of my Bio media is years old] until it is physically disintegrating or not effectively housing my BB,, I have no plans to change it. YMMV .

    Lack of planning on your part does not constitute an emergency on my part.
    Why pretend there are no stupid questions? Actually, There are many stupid questions: "Should I drink this bleach?" Is just one example.
    Having said that, Just because it's a stupid question doesn't mean that it shouldn't be asked. It's better to know.

    A warm beer is better than a cold beer. Because nothing is better than a cold beer, and a warm beer is better than nothing.

    So as I switch filter media over to ceramics and aqua clear polyfiber filter pads...

    I do understand that when the ceramics are fully seeded the polyfiber pads will basically be scrubbers and secondary in terms of the bb, but is there ANY benefit at all to seeding the pads by floating them in a bio-bag with half of the old filter media as the ceramics seed with the other half... or is this one of those can't hurt, but you don't need it things?

    sure there's a benefit - any extra bb is a good thing - but it's not required.
    It's the amount of available ammonia that mostly dictates BB matter how much filter media you have, you are only going to have so much BB in your tank as what your fish will feed with their wastes.

    Nothing wrong with being careful or going the extra mile!
