I've seen almost all the sponge filter videos and not one is like yours. You explain everything in detail and name each part by its correct name. Nobody has done that. Excellent video ! 👍

[@TrafishAquatics]

Thank you very much!

[@mrcoolxoxo7007]

Bro, draw this out on a paper with the air hise connected and think about it.... Air gets forced to the bottom of the filter creating rising bubbles forcing nearby water to move with it pulling water through the sponge at a weak level. So all the filth will be on the outside of the sponge.

this is my idk numberth video and I still can't understand how these suck the water in , I can't find anny reason why the air would suck the water in order to go up.

[@TrafishAquatics]

It's called airlift, as the air rises it causes the water to follow behind it, the only way the water can get in is through the sponge so it then follows the air up and out the lift tube

[@timrussell89]

@@TrafishAquatics there are only a couple downsides I can think of. They take up room in the tank which to me is not a big deal and there is no way to run carbon if you ever have to medicate. This problem can be fixed just by doing some extra water changes to remove meds. Not deal breakers by any stretch of the imagination.

[@TrafishAquatics]

Both are valid, however if you do ever plan on running carbon there are sponge filters that have media baskets where you could add and remove media as needed, search powkoo sponge filter on Amazon and it's the green one, very neat design

Thanks for your time explaining about the filters. I have been using hang on the back filters for years and have come across the sponge filters on UTube videos. I remember as a kid you had to put the charcoal in the bottom of the clear plastic filter and then on top of that you put the white cotton type filter medium. Nice to know that that model has been improved upon. I have ordered two filters (sponge) for my two 30 gallon tanks which I will be setting back up soon.

[@TrafishAquatics]

Thank you, Function is the same with an airstone, you would have to cut the plastic tube inside and attach a price of hose with a tube.

[@Vildmis]

@@TrafishAquatics thanks! I just put a(brand new) spongefilter in my 54 liter (24g?) Tank, I didn't like the filter that followed because its freaking big, it has one of them stupid cartridges and the filter besides that is so small. I wanna take it and just go with the spongefilter, but if I do that I will loose the bacteria I have in that, and its a new aqaurium where I'm doing a fish-in cycle (long story short). I can't wrap my head around how to do it, any advice?

[@TrafishAquatics]

Let it fully cycle with both filters then just remove the one you don't want and check for the next few days for ammonia spikes, if there's none your good, bacteria can double thier colony in 24 hours if they need to

Hello! Firstly wanted to say I love your videos! They are super informative and I’ve learned so much! I just got a the dual sponge filter for my tank along with the tetra whisper pump and I was reading the instructions for the air pump and it said it should be 12 inches above water level. I was just wondering if that’s actually necessary? And what you do for your tanks? Thanks!

[@TrafishAquatics]

Thank you! Generally the reason for that is so that you don't get a back siphon during a power outage, but as long as you have installed a check valve it's not necessary. personally I don't run the check valves and all of my air pumps rest on the floor and I've never had a back siphon but you're a mileage may vary.

[@edward_grabczewski]

Do you need to buy an air pump to match the sponge filter. For example, could you use a Tetra Whisper 60 to drive the small sponge filter in a 5 Gallon tank?

[@TrafishAquatics]

You could but you would need an air flow control valve to turn the air flow down

Putting an air stone in a sponge filter results in smaller but more evenly dispersed bubbles which in theory would provide better flow through the sponge filter.

For a 15 gallon I would definitely keep running both as goldfish generally have a very high bio load so the more filtration you have the better, also do your best to keep nitrate readings under 40ppm to keep them happy and healthy!

Great video! Do sponge filters do a good job on picking up watse? And if so, when you take it out to clean it. Wouldn't the watse just float around the tank as you're pulling it out?

[@TrafishAquatics]

Dont expect performace like a canister or hob filter where they pick up full solid waste, the sponge filter will collect waste that your bacterial colonies have begun breaking down, you will get some wast that floats around when removing it but not much and they will just suck it back up within 24 hours

[@NStalgia070]

What you can do while cleaning the filter is put it inside a plastic bag while it's still running and under the water, close it so that when you pick it up the waste doesn't float back out into your tank. Then you can proceed to clean it with the aquarium water.

It all depends on your stocking level, most of my 55s I run one 60 gallon rated sponge on one side and an air stone on the other to help move waste to the sponge, If you have a heavy stocking 2 sponges would be better. The sponge I use is listed in the video description!

[@nickphillips7261]

Aquarium co op sell them but they are in US. Sellers also dont list the actual sponge grade on product listings on ebay and amazon ect. Some sponges look really fine and others a bit coarser. Strange that they dont list the sponge spec as its quite important.

[@TrafishAquatics]

The 20ppi is good if you have another form of filtration for water polishing, if your relying on the sponge to polish water as well a higher ppi is better, I personally use a higher ppi sponge

[@shannydawn3608]

I have a few questions hopefully you can give me some advice. I've been debating on selling the canister filter that came with a used 75g that I haven't setup yet. The filter is a eheim pro 3 and it takes up nearly all the space under the stand leaving no room for storage and I've noticed the floor of the stand is bowed down from the previous owner using this filter. Thankfully the structure is still okay. I'm thinking I could use a large sponge filter or maybe the large one stacked in the 75 gallon. Would that be enough? It won't be heavily stocked. And it will be a fully planted tank. Right now I have a penguin 375 on my 40 gallon I was also thinking I could use that with the sponge filters when I setup the 75 gallon. Last thing is, can you cycle a new aquarium using only sponge filters? It seems like it would be okay as long as its dosed with dechlorinator. Since I'm already using my hob I wouldn't be able to use it to cycle when I set up the new tank. I have read of using a used sponge from the established aquarium to jump start a new aquarium with the beneficial bacteria. Thank you for your videos I've learned alot.

[@TrafishAquatics]

Trying to figure what topic to talk about first lol. I guess basically we could start with saying you can technically cycle an aquarium without any filters in it at all As long as you have some kind of water movement and surface agitation. Bacteria would be able to colonize on any surface in the aquarium and would be able to establish the nitrogen cycle. The reason we use filters is because bacteria will colonize any surface, so we try to create a large amount of surface area in a small space using items that have very large surface area size versus volume size. That being said sponge filters have extremely high surface area for their size So they are extremely effective at providing good biological filtration capabilities. For a 75 gallon you can run one sponge filter on the far left side if you have an air stone on the right side creating circulation but if you're going to run an air stone I would just recommend a second sponge filter and run one in each back corner. If you're able to use a sponge filter in a pre-established tank for about 2 weeks and then move it to a brand new aquarium you're bringing along any bacterial colonies that are pre-established therefore jump starting the cycle and you're able to add a small bio load right away. I hope that all makes sense if you have any questions feel free to ask

Basically the bubbles upward motion pulls water through the sponge. All debris would be visible on the outside of the sponge and works on a very limited scale... If dirty enough, you won't have much if any water flow. How would you know?
