    They can be used either way...air driven or mechanical.

    If you are going to attach it to your mechanical filter, you should put it on the input side. Greatly increases your filtration. I have 2 attached to 2 small mechanical filters

    They work very well driven by and airpump and can help circulation in your tank, especially if you might have a dead zone.

    I am using 7 of them on various tanks and all are driven by an airpump. Love 'em!!!!!

    I use them in my livebearer tanks. They rock! they also make some specially for pre-filters.

    I have a 29-gallon with a fluval 406 - the water flow output seems too strong for a 29-gallon.
    Thought maybe putting this filter on the output side will help on the regulating the output flow.
    Planning to have discus on this tank.

    won't that create back pressure?

    Yes it will create back pressure, must be on the in-put side. If you have to controle the out-put you would have to an in-line valve on the in-put side, I did this before on a canaster filter it worked for me

    Thank you. Any chance of a diagram?
    Also what is the water flow on this? Air goes in the middle tube? Then what?

    Thanks.
    So the air bubbles is the filtered water & serves as aerator at the same time?

    Yes, it creates a very gentle current. It's great for fish that prefer still waters or especially fry since they won't get sucked up.

    :;thx

    What kind of filtering is this?
     
  12. Cichlidnut Fishlore VIP Member

    It's biological filtration. Bacteria colonizes inside the sponge.

    Any idea how long the filter need to be in the aquarium before it can be considered as "colonized"?
    Also tank has to be cycled to use this kind of filter?
     
  14. Cichlidnut Fishlore VIP Member

    You can cycle with it just like any other filter. It will probably take a month to be fully colonized.

    Ok.

    You can just put in some old filter media from another tank in the middle. Leave it there for like a week or two then you can take the old media out. Instant cycle. Or just use Tetra SafeStart.

    I don't recommend an airstone in it.... more water is moved by bigger regular bubbles. Just the airline works the best. I even have extended the air line deeper into the filter and get a nice gentle current out of them. Adjust your air pump to move the most water with the least splashing or put a pvc right angle connecter on it to disperse the flow away from the filter and out into the tank.

    appreciate your further input.

    using it now as an aerator basically for a 55-gallon tank with 2-fluval filters. I would think that in a month-time or more I can transfer it to any tank and should be bacteria loaded by then.

    planning to used it when it is ready in a breeding tank - to avoid the strong current outflow of a fluval.

    Good plan! I would give it at least a month, if not a little longer to get a good colony built up. Once it has the bacteria you are good to put it in to any tank you'd like.

    I use sponge filters in all my tanks that have fry in them. They work very well, allowing fry to find food as well.
