    Thanks, Crispy.

    Comes in various sizes, dirt cheap and works well. With these you just pop off the bottom and you can get at the sponge. There's a hollow in there filled with carbon and plugged with some sponge. Most knowledgable people just chuck the carbon and replace with some small glass sinter balls. Maintenance is easy enough, draw some tank water, shake out the ceramics in the bucket. Squeeze the sponge a bit and reassemble. My daughter's shrimp tank runs on one of these.

    If a cartridge doesn't allow for easy disassembly then in my opinion it's not a viable solution for any serious aquarist.
    I have a 60 gallon (U.S.); not exactly small, but not massive either...I'm kinda happy with my HOBs, though...

    I've never heard that. Filters in general can become nitrAte factories if not properly maintained, but it has nothing to do with the carbon leeching. This is because they trap debris/waste which decomposes in the filter pad creating ammonia which is converted to nitrate. If a filter is not cleaned out on a regular schedule then more and more waste will build up. By cleaning out the filter and removing the excess debris, it's like preemptively doing a water change because you're removing the nitrates before they had a chance to form. It's the same reason people clean the bottom of the tank with a gravel vac. Having the debris in that form is completely harmless (although it may look bad) but it will eventually break down causing nitrate and other pollutants. On the contrary, I never clean the bottom of my tank because it's heavily planted and the waste at the bottom will just be fertilizer for my plants.
    Understood, Funk; thanks...

    You can actually skip the cartridges for these filters all together. What most people don't know is, the filters run just great by making your own filter media, either by cutting to fit filter pads to go into the pull out housing for the cartridge, or, just stuffing the back with a cut to fit filter sponge block. I also know several fish keepers who have simply stuffed them with filter floss, works just fine. If using stuffed in sponge block or filter floss, just dump in some bio rings at the bottom, and your all set for when you need to change out media.
    2 10 gallon tanks, 1 20 gallon tank, 1 Fluval Edge, 1 29 gallon tank, and one backyard pond.

With their line of QuietFlow filters come "bio-grids" and "diffuser grids" which are supposed to grow and house the bacteria supply -- and which are not recommended by the company to be rinsed or otherwise cleaned in any way because of this -- thus allowing the actual cartridge pads to be discarded without fear of going into a mini-cycle...
    This is the part that I find interesting. As discussed already, most seasoned fishkeepers will use different cartridges for mechanical and biological filtration so that when the mech filter (such as polypad) is thrown away, the biological capacity of the filter is relatively untouched. When using just a mech filter, that's the majority (but not all) biological activity is believed to be, so essentially every time you throw out your clogged polypad, you're also throwing out your bacteria and cycling the tank all over again. Now I said that not all the bacterial activity is in the filter because it pretty much covers all of the wet surfaces in the aquarium as well as in the sand, but is that enough to prevent a cycle every time you throw out a filter cartridge? I'm not exactly sure myself since I've never owned a filter without a separate biofilter cartridge so I have no evidence (such as ammonia tests) to plead a case.

    I have read peer reviewed papers that have shown that activated charcoal (what people here call carbon) absolutely does leech some types of chemicals back into the water after a long time. Charcoal should always be replaced after (no one knows the time period) point that it becomes useless.

    As always, people disagree and I am tried of this argument. Fact is, that some things will not be released from charcoal and some will - depends on the chemical’s action with the charcoal; most are held by simple Van de Waals forces and this is a very weak bond. Chemicals held by such forces will, to varying amounts, leech back into the water as the charcoal becomes saturated. Others will form stronger bonds and not leech to any measurable extent. When and until someone does a study relative to common chemicals that charcoal ‘holds’ from a tank – anyone here know any such chemical common to most aquarium’s? If so, please let us all know but so far, have never read of any such chemicals posted by anyone – till then I will say, except for specific reasons like med removal or a known dangerous organic getting into the water, charcoal is a waste for most people to use.

    Next, outside of the bio-media in the filter(s), the bacteria on other surfaces is of no value for filtering waste in any tank because it is so vastly outnumbered by the bacteria in the filter media. You must save the filter media when cleaning a filter - never throw that out.

    lol last time we discussed this I posted an article which proves that it doesn't leech under normal conditions, and asked you to post an article stating otherwise, and you disappeared and failed to show me anything. Nice try though.

    LOL is typical of people who know little and post claims without facts. Please, tell me how charcoal bonds to chemicals in a manner that prevents leeching.
