Great step by step tutorial! Thank you !

I just did this! Now it no longer sounds like a witches brew in my shrimp tank 🤣

I keep coming back to your video when I forget how this is done. Been back several times. Well done.

Thank you very much Anthony Big hugs from Malta. I just modified one little sponge filter as I have some Angelfish wiggles and i actually wanted to put an air stone as well in the little tank, but I don't have an extra air pump so this way it seems I did both. Thank you again! :)

Thanks for the great video explaining exactly how to place the air stone in the sponge filter. All my stuff came from Aquarium Co-Op as well

The airstone improves the performance of a sponge filter. Instead of large intermittent bubbles the airstone produces a constant stream of smaller bubbles that continuously draws water through the sponge.

Thanks for explaining so well and mentioning why yours was double the parts inside !

Brilliant mod. Just got the large sponge filter from Amazon. Your instruction are a breeze. Just about to throw it in the tank. Thank you! Cheers!

Thank you sooooo much!! One of the only videos on KZfaq that gets straight to the point with step by step instructions. You got a new subscriber now because of so. Take care and stay well.

Ive just done this step by step with you (a bit of pausing and rewinding lolx) and its great thank you, you explain it very well, compared to some sites, so thank you.x With Love from the UK.x

Starts at 2:45

Best video yet. Even showed how to cut out the plastic ring piece. Thanks u made this very easy to understand

I'm definitely doing this to all my sponge filters! Thanks for the video!

I’ve been trying to figure out how to assimilate the air stone with the new sponge filter that I installed last night in my 10 gallon Betta tank. I love the sponge filter so much more than the hang on the back one I had. What a nice difference. Great video with step by step instructions.

Great tutorial! I have a sponge filter fit for a 10 gal tank and had to add a few more steps to make the stone fit in the filter (just shortening everything because the stone was too big) but thanks to this simple easier to understand tutorial it works great!

Thank you so much this was a huge help im new to tanks and filters and everything. This really was a clear step by step and I was able to get it done ❤

This was so helpful, thank you so much!!! Pliers and scissors worked for me!

I have a small tank and the sponge filter I had was way too big, but it had 2 parts like yours. I cut the sponge in 2 and remove one half and it works very well.

Idk if you'll ever see this, but you sir are a hero. When im at my darkest, and no one to turn to for sponge filter air stones, you are there to save the day.🫡 I have a >10 gallon sponge filter from Aquaneat i just bought, and they have zero air stones to use in the filter. I ended up buying top fin air stones from petsmart hoping that they would, but they arent compatible with other sponge filters.i followed your directions, and i also had to cut out the bottom part that anchors to the weight, but it worked afterwards!! Thank you so much🙂

way better instructional demo than those brand name channels showing some stupid diagram. thanks bro

I have a barrel pond outside and just bought a solar air stone this is a great mod to make my air stone a filer as well thanks!

Ah! I didn't think to cut the part of the middle tube to attach to the top of the inside of the filter! The way I got around it was to cut the centre hole out of the top of the filter (leaving 4 spokes) and fed my airline directly through attaching straight to my air stone. Your way seems a lot neater so I will try it next time - thanks!

Thank you for this! Used this hack and it worked beautifully!

thanks for this. my sponge filter was smaller and the air stone was slightly bigger than the inside compartment so i had to make some adjustments so it could fit. but it works like a charm and my betta is a happy camper!

I ran my tubing through the gaps in the top lid section rather than using that bit you cut off, found it far easier lol

Bubbles dont put O2 into the water no matter what the size of the bubble is. What "puts" O2 into the water is the gas exchange that occurs where water meets air. The agitation of the bubbles on the water surface is what increases the level at which CO2 and O2 exchange.

You only need to cut the bottom one and attach the airstone to the top one with airline.

Hi do you have any links for filters and air stones that ship to the UK. Really helpful video though does any airstone work or does it have to be a certain size?

Absolutely great video. Exactly what I needed. And the instructions were clear cut and to the point without side trips. Keep it up!!!!

With the larger sponge filters there's no need to put up with air bubbles bursting all over and the noise of an air pump. Fit a piece of 1" pvc over the outlet on the filter and chop it off around four inches or so from the surface. Place a power head on top and plug it in. More water flow, more surface agitation, almost no sound and the best part is the power head will likely outlast two or three air pumps and a bunch of air stones.

I tried this! Thank you very much it definitely helped me

One could even add an air flux valve so you can finely tune the flux of the bubbles (sorry for my bad english

Thank you for the tutorial

Perfect angle on your filming!! It seems like all the other videos I watched their hands were in the way.

What wasn't mentioned was (1)to consider the need for a non- return valve above the filter and (2) to squeeze the filter when under water to get rid of air in the sponge.

Great video. Thanks.

The air stone that I have seems to be too large for my mini sponge filter. Do air stones come in different sizes?

Worked like a charm! Thanks.

Thanks for doing an actual step by step process! Much appreciated!

I have a 1” air stone in the sponge filter. Would adding a 2” be better? The sponge filter I have is for a 60 gallon tank. The sponge is 5.5” high and with the air tube is 8” high. A 2” air stone would take up a little less then half of the inside tube. I was wondering if it mattered what size air stone you have inside.

This is so much better! Thank you!!

Super helpful, really nicely produced video, thanks!

Very helpful! I am confused though how the air gets into the bottom chamber when the air stone just sits on the bottom without being connected like the tubing would be...?

Hi, why can't you just remove the lids Connection and have the air hose as one piece, from pump to stone?

ooh this video was made on my birthday

I have done this and now i want to introduce floating plant salvinia. Will the plant thrive or die due to the airstone placement

This video helped me greatly. Subbed

Exactly what I needed to know, thank you~!

Thank you helped me works sooo good!😊

This works great, I only use sponge filter on hospital & birthing tank, I could not tolerate the loud gurgling, this reduced noise to almost nothing, filter works just as well and aerated better, surprised something like this isn’t manufactured, but this hack works great and easy to do, just follow the video.

thanks for this vid, I got my co-op order today and had no idea how to attach the airstone when I saw the new sponge! new sub 😊 what do you think of how fine these new sponges are compared to the old ones? the difference is huge!

I was looking for this - thanks

Thanks, I was wondering which end the air stone needed to go.

THANK YOU. Fast becoming THE standard video for doing this right. ONE down, three to go! PS: can you tell me what BRAND that black air stone is? A link even - nobody seems to have them in my local area.

I like the reducing the noice with the airstone set up. Can this mod be done witht the double barrel sponge filter? Really like how you explain and demonstrate. Good stuff.

great video this really helped!

very excited to try this mod after work today, thank for the vid! just hoping an air stone will fit inside a nano sponge filter...

Thanks for posting. As it turns out the sponge filters I got from amazon are built exactly like this- and have no instructions at all.

I am putting a sponge filter in my tank for the first time of I dont mind the noise do I really need to put an air stone in the sponge filter

Excellent instructions, thank you!

hey duke is it better to cut the inside? i have a sponge filter but i never did this.

I did this to both my sponge filters and i'm going to be buying new ones. I noticed that will the air stone it wasn't catching uneaten fish food like it was before I cut the air diffuser out.

Does this still work as filter ? How does the water get sucked up now through the sponge.

What if you plug the top of the tube with a mesh filter will it shrink the bubbles even more creating more oxygen 🤔

Thank you 😊

Thank you for sharing this video 👍😀

Thanks!

Great idea. Thanks for sharing.

Thank you so much for this tutorial!

I got a sponge filter for my 55 gal and the big bubbles with really noisy and bothering me. It works way better now

20 gallon 2 sponge filter is enough or HOB with it?

And air bubbles also breaks the surface tension to also add air.into a tank and wave makers acts the same way it breaks r the surface tension

Why don't they just make them so the bubbles are tiny in the first place? That would be a big seller I'll bet. I have been trying to do this all night.

Does it matter where within the sponge filter’s core the air stone is situated? E.g., bottom of the core like you have here, middle, closer to the top, etc.?

Thanks sir...for the tutorial🤗

i like the sound it relaxing to me really not bother by the bubbling!

gréât vidéo, very well explained, thank you, i wii try it.

Great stuff, thanks.

It’s a cool hack but the efficiency of the filter will be affected. The air stone restricted the air flow and that will weaken suction through the sponge.

Will that decrease the suction of the sponge

Amazing idea 👍👍

The filters that point to aquariumcoop already come airstone ready. Also wouldn't the tubing already fit the top base where the little piece you cut off fits into? It may just be that this video came out before they had those specific filters. My fail I did something similar with a walmart airstone, lowered air with a valve and the stone now sounds like it's spitting water every now and then. The pump is rated for my size tank but even w/o airstone it throws more air(louder). I do want to try one of those no-clog air "stones" (I believe it's felt and plastic) nevertheless it's annoying having to hear the regular ones.

This helped a lot thank you

Going to be using the modification when I set up my tanks again in two weeks. The box stores do not carry the sponge filters. The mom &pop stores charge $20.00 for one filter. I ordered the three pack of sponge filters on Amazon for 16.00 bucks and change. I also am going to add some charcoal to the inner corridor where the air stone is placed. Thanks for the information.

I bought my sponge filter but I had no tubing so how do I use it

Hello! Great video. Anyone know where to buy just the uplift tube for large sponge filter?

Good mod. I’ve been modifying my ATI sponge filters with air stones for years. Far easier to modify the ATI then the cheaper sponge filter you demonstrated on. That said, if you don’t modify those cheaper sponge filters then you’ll notice them clogging a lot quicker - at least that has been my experience. Curious why you don’t use lids on your tanks. It will help reduce evaporation and eliminate any jumping fish from taking a fatal plunge.

Excellent!

Why would u need the small tubing? Why not just leave on long tubing?

Muito obrigado!! Seu tutorial me ajudou muito e ainda deixou meu filtro esponja mais silencioso😉

Very complicated way way of doing easier but twin airpump one for sponge one for airstone and no stressed

I’m really trying to learn... I thought more surface disruption the more it will release CO2 hence the more oxygen, but what i get from this is, the more bubbles from the air stone get the tank more oxygen from bubbles but disrupt the surface more, it’s like they both equal out! My goal is, I have a sponge filter, I’m a beginner and have a planted tank have have shrimp and snails in it, I hate the big bubbles that splashes on my light and leave hard water spots, but the smaller bubbles seam like they would leave more. I wanna keep as much CO2 in the tank for the plants without adding CO2, what have you found best to keep CO2 but keep from splashing? Air stone or no air stone?

I just run the tube through from the bottom. I couldn't connect to the bullseye as the connection point was too wide for the tube, so I broke the middle of the bullseye to run the tube direct from the pump to the air stone at the bottom of the filter.

Do you need to rinse the new sponge filter before putting it in the tank?

I did that today before watching your video...and i throw away that small piece....hehheheh....o well live and learn

won't this decrease the filtration capacity?

i just discover it today putting seastone inside the Sponge filter to maximize the the outputwith other video but i watch your how to connect if cleanly ang i got how to do it properly thank you

Cut the entire tubing inside then reuse a small part of it to reattach it again?

DCA - I'm in the Duke City as well. Just getting back into the hobby after a few years and moving house. I'd like to get together to share ideas, knowledge etc. Whaddya say? One question I have is - can you add a stone with a power head attached to the sponge filter?

Air has 02 in it and every living thing needs oxygen to survive fact .so adding more air into a tank does add 02 into the tank .I have big powerfully air pumps on my tanks nothing less than 4 outlets most are 12 outlets pumps that run 2 ,4foot tanks 90 cm bubble bars ,30cm air stones ,wave makers , 4 lge sponge filters and a 2.000 ltr canister pumps to every tank .also if you point your wave maker to the surface of the water angled to one side.it will actually work in a circular motion that.will shift the wast food and poop inthe direction of the canister.pump and sponge filters that keep the tanks cleaner at the bottom of the tanks . And think about what happens when the power goes out how do the fish react they come to the surface of the tank for oxygen
