    Hi everyone
    I’m trying to find out the pros and cons to replacing my air stone with a small sponge filter in addition to my HOB
    Does it help?
    Is it goanna make it worse?
    No effect?
    More noise?

    It would add another good place for beneficial bacteria to live and provide filtration + oxygenation. An air stone just provides oxygenation.

    You'd use the same air pump, so it would sound the same.

    Is there a reason you might swap it, and is there any particular reason you have the air stone now?

    No i just had the airstone as an oxygenation device for the past 2 years and my 20g is cycled well but as it uses the same pump and tubing i was thinking of switching for more filtration
    If I switch to sand substrate from gravel and a bit of redecorating so it could be a useful option

    More filtration is always good. You can also put a prefilter on the HOB intake to increase it.

    I'd consider switching it as I think a sponge has more benefits. Additionally, if you ever wanted to quickly set up another tank, maybe hospital or QT, you could move that seeded sponge over if needed.

    (I switched from gravel to black sand and really like it better.)

    Basically by swapping the air stone to sponge filter, there is generally just pros. The only con is maybe the sponge taking more space up in the tank.

    Sponge filter uses air stone anyways, so ahead and get one. has large sale on Azoo sponge filters.

    There are also good if you need to use a 5 gallon bucket for a quarantine or hospital tank.

    Just take it out of the 20g and throw it in bucket for instantly cycled temporary tank.

    It will provide much more oxygine then an air stone. It will house cycling bacteria. It will hold the tank cycle if/when you need to clean/rinse/change the filter or filtercartridges in the HOB.

    It helps water flow and filtration and is a home for shrimps

    IMO the sponge filter adds more benefit than just a bubbler. Go for sponge filter if you have the space for it in your tank.

    Also if the HOB were to need servicing or breaks, you have the sponge filter working just in case. Sometimes also when using a bubbler bar it can create a strong up current and really stirs the water around. I myself have a HOB and a sponge filter in every tank.

    So i added a small sponge filter that made a safe place for fry

    And today I changed it to a bigger one and put the small one in my other smaller tank
    Happy with it me and fish
