How Do Sponge Filters Work?


Hey. Today I’m going to cover the question: how do sponge filters work. So, these are sponge filters. When you go out and buy an aquarium, you’re gonna get sold a filter, obviously, because we need to filter our aquariums and what’s gonna happen is the pet store or whatever is gonna try and sell you like a hang on back filter or like a canister filter, or something like that.

There’re a few reasons why. Basically, canister filters and hang on back filters have a lot of like accessories so like filter pads and media, and things like that which needs to be replaced quite often. So, you can already see the scheme of events. What’s gonna happen is you’re gonna buy a really expensive filter and then there’s gonna be a lot of media upgrades and replacements, and things like that.

In cases you’re gonna have to go and buy more that stuff from the pet store. So they’re gonna keep getting money, and yet with these guys you don’t have any other stuff.

How Do Sponge Filters Work

Sponge filters are a very cheap alternative to filtration in an aquarium, and they pretty much do the exact same job. Keep reading and you’ll learn how do sponge filters work, why to keep them and why a lot of other people in the aquarium world will be keeping them.

Sponge filters cost normally around six to eight dollars, sometimes a little bit more. There’re normally two styles we can get.

  1. This is gonna be more of a sinking style of filter. That’s going to sit on the bottom of the aquarium and then it’s going to have an air intake going through the tube.
  2. We can also get a wall-hung like. They’re going to sit on the opposite side of the aquarium. They’re going to have a little tube. That’s going to take the air pump in there.

We are getting closer to how do sponge filters work. Basically, it’s really simple how they work. What’s going to happen is going to have an air pump and the air pump is going to pretty much use true to blow air into the body of the filter.

Inside the filter, we’ve got two media parts. What are these for? These are obviously for taking out little pieces of particles and things like that in the water, but they’re also for the most important thing in a filter and that’s the beneficial bacteria.

They are going to help you in the nitrate cycle of the aquarium and they’re going to make sure that you get all the denitrifying bacteria to start doing their job and making that aquarium work. They saw these guys sit there and they obviously act as the filtration. But what you’re going to have is two intakes here. So, what’s going to happen is it’s going to be blown into the tubeб and in the air, it’s going to come out.

There’s another little hole inside it. What’s going to happen is there’s going to be pushed out of here and then after this, the bubbles obviously going to rise to the top of the surface of the water. So, this is going to be full of water.

When you add this to your aquarium in the bubbles, in a rise to the top and start coming out, the top and the thing that happens with the water in the suction part of this, is that or when these bubbles are coming up.

So, it creates a lot of momentum. Upwards, in turn, creates a lot of suction, so water’s going to be sucked from these little intakes here. As you can see, these will have your filter media over top of them, and these are going to suck in water and as these bubbles are coming up. That’s how do sponge filters work.

So, these will sit on here. They’re going to collect all over that, like debris, that’s coming through. They’re not very powerful, obviously, depending on how much air you’re blowing into the tube. But a lot of people think, how they’re actually sucking up anything into the filters because they are very thick and they’re not going to let any water through it.

fishThese guys do a really good job of taking debris out of the water and every month I clean my sponge filters, I squeeze a mountain. There’s so much debris in there, so they do a really good job of taking out small particles in the water and filtering the water. So that’s how they work. They pretty much work by just pumping air into them and then, when the air tries to go out the surface again, it rags up a lot of water with it.

The sponge filters take advantage of this sort of factor, like obviously the suction, and then they use that to filter your water. So, the sinking sponge filters work the same there pretty much. If we open them up, they have a little hole like the one. You can see here there’s flow into the bottom of this, and that creates the flow upwards. A lot of water is sucked through the sides of this, so this orbit holes around.

It’s like a cage and water gets sucked through the side of this and pulled up by the bubbles that are going to the top of the water and that’s how they work. It can be really confusing. The other thing that happens when you use these filters in your aquarium is that they actually add a lot of oxygen to the water because they have to suck water through little holes and pour the things like that. So, they do a really good job of aerating your water and you get a two-for-one kind of deal here, and yeah, that just work with it really well.

I hope I managed to explain how do sponge filters work.
