External Filter - Can It Overfill?

    Hello
    is there a possibility for an external water filter (below is the one I use) to begin malfunctioning and overfill, and spill the water outside the tank, on the floor?
    We just put hardwood floor and my husband would "kill me" if I ruin the floor with my fish tanks :)

    Thank you

    Probably possible, but highly doubtful.

    You can always go with a sponge filter if you are that worried about it, but..... then you have to get an air pump, which IMO is one of the most annoying sounds in the world haha!

    The only way I can see it overflowing is

    1) the filter cracked and leaked while the pump was still bringing in new water

    2) something blocked the water from flowing back into the tank. The pump may continue to bring in water with no where to go but out the sides.

    But any sort of other malfunction would typically mean the pump stops working, which would stop water from entering the filter at all

    Thank you.
    I know what you mean about the air pump. I have 2 more tanks ( 2.5 gal cookie jars) with 2 bettas. And I moved them in a different room because I could not work. The air pump is silent: phantom Cobalt Ultrasonic . But the bubbles in the tanks were driving me insane.

    Thank you.
    I've been having this for over an year and it never had an issue.
    One more question. How often should I change the internal filter? I have never done it so far.

    do you mean the filter cartridge? I never change mine. Just swish them around in old tank water to get the gunk off. Switching cartridges completely will get rid of your beneficial bacteria and restart your cycle

    You can probably test the filter by filling a cup or pitcher full of tank water and pouring it into the top of the filter behind the filter cartridge. Watch where the water goes when there is more coming in than can pass through the filter cartridge. In other words, you want to see what happens if the filter cartridge is clogged.

    Hi! I also have hardwood floors and no it cannot unless your tank starts tipping. Even if the pad gets clogged it wont fill up and spill out the back instead it will flow back out over the thbe that sucks the water up. Essentially the water will go in the filter, go up a little, and spill right back into the tank. The water level will bever reaxh the top of the filter or spill over unless its hanging horizontally
